Numonyx® Embedded Flash Memory (J3 65 nm) Single Bit per Cell (SBC)

2.0 Functional Overview

The J3 65 nm SBC family contains high-density memory organized in any of the

following configurations:

• 16-MB or 8-M W ( 128-Mbit) , organize d as one - hundred- twenty-eight 128-KB erase

blocks.

• 8-MB or 4-M W (64-Mbit) , organized as s ix ty- four 128-KB erase blocks.

• 4-MB or 2- M W (3 2- Mbit), organized as thirty-two 128-KB erase bl oc ks.

These devices can be accessed as 8- or 16-bit words. See F igure 1, “Memory Block

Diagr am for 32-, 64-, 128-Mbit” on page 11 for further details.

A 128-bit Pro tectio n Re gist er ha s mult iple uses, inc ludin g unique flash d evice

identification.

The J3 65 nm SBC device includes new security features that were not av ailable on the

(previ ous) 0.13µm v ersions of the J3 fami ly. Thes e new security features prevent

altering of code through different protection schemes that can be implemented, based

on user requirements.

The J3 65 nm SBC optimized architecture and interface dramat ically increases read

performance by supporting page-mode reads. This rea d mode is ideal for non-clock

memory systems.

Its Common Flash Interface (CFI) permits software al gorithms to be used for entire

famil ies of devi c es . This allows devi c e - indepen dent, JE DEC ID-indepen dent, and

forward- and back ward-compa tible software support for the specified flash device

families. Flash vendors can standardize their existing interfaces for long-term

compatibility.

The Scalable Command Set (SCS) allows a single, simple software driver in all host

systems to work with all SCS-compliant flash memory devices, independent of system-

level packaging (e.g. , memory card, SIMM, or direct -to-board pl acement). Addition ally,

SCS prov ides the highest sys tem/devi c e data transfer rat es and minimizes device and

system-level implementation cos ts .

A Command User Interface (CUI) serves as the interface between the system processor

and internal operation of the device. A valid command sequence written to the CUI

initia tes de vice aut oma tion. An inter na l Writ e State Mac hine (WSM) automatically

executes the algorithms and timings necessary for block erase, program, and lock-bit

configuration operations.

A block erase operat ion erases one of the devic e’s 128- K B blocks typically within one

second, independent of other blocks. Each block c a n be independen tly erased 100,00 0

times. Block erase suspend mode allows system software to suspend block erase to

read or program data from any other blo c k. Simi la rly, program s us pend allows s ys tem

software t o suspend progr ammin g (byte/w ord progr am and writ e-to-buffe r operat ions)

to read data or execut e code from an y oth er block that is not being suspended.

Each device incorpo rates a Write Buffer of 256-Byte (x8 mode) or 256 -Word (x16

mode) to allow opt imu m programming perform a nc e. By using the Writ e Buffer data is

prog ra mm e d more eff i cientl y in buffer increme n t s .

Memory Blo c ks are selective ly and individually lockable in-system. Individual block

locking uses block lock-bi ts to lock and unlock blocks. Block lock-bits gate block erase

and program oper ations. Lock-b it configuration operations set and clear lock -bits (using

the Set Block Lock-Bit and Clear Block Lock-Bits commands).

The Status Register ind ic a tes when the WSM’s block erase, pr ogram, or lock-bit

configuration operat ion completes.

The STS (status) output gives an additional indicator of WSM activi ty by prov iding bo th

a hardware signal of status (versus software polling) and status masking (interrupt

masking for background block erase, for example). Status indication using STS

minimizes both CPU overhead and system power consumption. When configured in

level mode (default mode), it acts as a RY/BY# signal. When low , STS indicates that the

WSM is performing a block erase, progr am, or lock -bit config uration. STS-high indicate s

that the WSM is ready for a new command, block erase is suspended (and

progra mming is inact ive), program is suspended, or the device is in reset / power-down

mode. Additionally, the configuration command allows the STS signal to be configured

to pulse on completion of programming and/or block er ases.

Three CE signals are used to enable and disable the device. A unique CE logic design

(see Table 17, “Chip Enable Truth Table for 32-, 64- , 128-Mb” on page 30) reduces

decoder logic typically required for multi-chip designs. External logic is not required

when designing a single chip, a dual chip, or a 4-chip miniature card or SIMM module.

The BYTE# signal all ow s either x8 or x16 read/writes to th e device:

• BYTE#-low enables 8-bi t mode; address A0 selects between the low by te and high

byte.

• BYTE#-high enables16-bit operation; address A1 becomes the lowest order

address and address A0 is not used (don’t care).

Figure 1, “Memory Block Diagram for 32-, 64-, 128-Mbit” on page 11 shows a device

block diagram.

When the device is disabled (see Table 17, “Chi p Enable Truth Table for 32-, 64- , 128-

Mb ” on p age 30), with CEx at VIH an d RP# at VIH, the standby mode is enabled. When

RP# i s at VIL, a further power-down mode is enabled which minimizes power

consumpti on and provides w r ite protectio n du ring reset. A reset time (tPHQV) is

required from RP# going high un til data out puts are v alid. Likewise, the device has a

wake time (tPHWL) from RP#-high until writes to the CUI are recognized. With RP# at

VIL, the WSM is reset and the Status Register is cleared.

4.3 S ignal Descriptions

Table 3 lists the active signals used on J3 65 nm SBC and provides a description of

each.

Table 3: Signal De scriptions for J3 65 nm SBC

Symbol Type Name and Function

A0 Input BYTE-SELECT ADDRESS: Selects between high and low byte when the device is in x8 mode. This

address is latche d during a x8 program cycle. Not used in x16 mode (i.e., the A0 input buffe r is

turned off when BYTE# is high).

A[MAX:1] Input

ADDRESS INPUTS: Inputs for addresses during read and program operations. Addresses are

internally latched during a program cycle:

32-Mbit — A[21:1]

64-Mbit— A[22:1]

128-Mbit — A[23:1]

DQ[7:0] Input/

Output

LOW-B YTE DATA BUS : Inputs data during buffer writes and programming, and inputs commands

during CUI writes. Outputs array, CFI, identifier, or status data in the appropriate read mode. Data

is internally latched during write operations.

DQ[15:8] Input/

Output

HIGH-BYTE DATA BUS: In pu ts data dur in g x16 buff er write s and pro grammin g ope rations.

Outputs array, CFI, or identifier data in the appropriate read mode; not used for Status Register

reads. Data is internally latched during write operations in x16 mode. D[15:8] float in x8 mode.

CE[2:0] Input

CHIP ENABLE: Activates the 32-, 64-, 128-Mbit devices’ control logic, input buffers, decoders, and

sense ampl i fiers. When t he device is de-selected (see Table 17, “Chip Enable Truth Table

for 32-, 64-, 128-M b” on page 30), power reduces to standby levels.

All timing specifications are the same for these three signals. Device selection occurs with the first

edge of CE0, CE1, or CE2 that enables the device. Device deselection occurs with the first edge of

CE0, CE1 , o r CE 2 that d i sables the device (see Table 17, “Chip Enable Truth Table for

32-, 64-, 128-Mb” on page 30).

RP# Input RESET: R P#-low resets internal automation and puts the device in power-down mode. RP#-high

enables normal operatio n. Exit from reset sets the device to read array mode. When driven low,

RP# inhibits write operations which provides data protection during power transitions.

OE# Input OUTPUT ENABLE: Activates the device’s outputs through the data buffers during a read cycle.

OE# is active low.

WE# Input WRITE ENABLE: Controls writes to the CUI, the Write Buffer, and array blocks. WE# is active low.

Addresses a nd da ta are latch ed on the risin g ed ge of WE#.

STS Open Drain

Output

STATUS: Indicates the status of the internal state machine. When configured in level mode

(default), it acts as a RY/BY# signal. When configured in one of its pulse modes, it can pulse to

indicate progr am and/or er ase completion. For alternate configuration s of the Status signal, see the

Configur atio ns command and Sec tio n 9.7, “St atu s Si gnal” on page 41. STS is to be tied

to VCCQ with a pull-up resistor.

BYTE# Input

BYTE EN ABLE: BYTE#-lo w plac es the devic e in x8 mode; data is input or output on D[7:0], while

D[1 5:8 ] is pl ac ed in H igh - Z . A ddress A0 sel e ct s b et we en th e hig h and l ow by te. BY T E# -h ig h pl ac es

5.3 Power-Up/Down

This section provides an overview of system level considerations with regards to the

flash device. It includes a brief description of power-up/down sequence and decoupling

design con s iderat ions.

5.3.1 Power-Up/Down Sequence

To prevent conditions that could result in spurious program or erase operations, the

power-up/power-down sequence shown in Table 6 is recommended . For DC voltage

characteristics refer to Table 8. Note that each power supply must reach its minimum

voltage range before applying/removing the next supply voltage.

NOTICE: This document contains information available at the time of its release. The specifications ar e subject to change without

notice. V e rify with your local Numonyx sales office that you have the latest datasheet before finalizing a design.

Storage Temperature –65 +125 °C —

VCC Voltage –2.0 +5.6 V 2

Voltage on any input/output signal (except VCC, VCC Q) –2.0 VCCQ (max) + 2. 0 V 1

ISH Output Short Circuit Current — 100 mA 3

Notes:

1. Voltage is referenced to VSS. During infrequent non-periodic transitions, the voltage potential between VSS and input/

output pin s ma y u nd ershoot to –2.0 V for pe r iods < 20 ns or overshoo t to VCCQ (max) + 2.0 V for periods < 20 ns.

2. During infrequent non-periodic transitions, the voltage potential between VCC and the supplies may undershoot to –2.0

V for periods < 20 ns or VSUPPLY (max) + 2.0 V for periods < 20 ns.

3. Output shorted for less than one second. No more than one output pin/ball can be shorted at a time.

Note:

1. Power su ppl ie s connected or se qu enced togethe r.

Device inputs must not be driven until all supply voltages reach their minimum range.

RP# should be low during power transitio ns.

5.3.2 Power Supply Decoupling

When the dev ice is enabled, man y internal condition s change. Circ uits are energ ized,

charge pumps are switched on, and internal voltage nodes are ramped. All of this

internal activities produce transient signals. The magnit ude of the tr an sie nt signals

depends on the device and system loading. To minimize the effect of these transient

signals, a 0.1 µF ceramic capacitor is required across each VCC/VSS and VCCQ signal.

Capacitors should be placed as close as possible to device connections.

Additionally, for every eight flash devices, a 4.7 µF electrolytic capacitor should be

placed between VCC and VSS at the power supply connection. This 4.7 µF capacitor

should help overcome voltage slumps caused by PCB trace inductance.

5.4 Reset

By holding the flash device in reset during power-up and power-down transitions,

inv alid bus conditions may be masked. The flash device enters reset mode when RP# is

driven low. In reset, internal flash circuitry is disable d and outputs are placed i n a high-

impedance state. After return from reset, a certain amount of time is required before

the flash device is able to perform normal operations. After return from reset, the flash

device defaults to asynchronous page mode. If RP# is driven low during a program or

erase operation, the program or erase operation will be aborted and the memo ry

contents at the aborted block or address are no longer valid . See Figure 12, “AC

Waveform for Reset Operation” on page 2 8 for detailed information regarding reset

timings.

Notes:

1. CEX low is defined as the combination of pins CE0, CE1, and CE2 that enable the device. CEX high is defined as the

combin ation of pins CE0, CE1, an d CE2 that disab l e the devic e (s ee Table 17, “Chip Enable Truth Table for

32-, 64 - , 128-Mb” on page 30).

2. Read timing characteristics during block erase, program, and lock-b it configuration operations are the same as during

read-only operations. Refer to AC Characte risti cs–Re ad-Only Oper ations.

3. A write operation can be initiated and terminated with either CEX or WE#.

4. Sampled, not 100% tested.

5. Write pulse width (tWP) is defined from CEX or WE# going low (whichever goes low last) to CEX or WE # goin g hig h

(whichever goes high first). Hence, tWP = tWLWH = tELEH = tWLEH = tELWH.

6. Refer to Table 18, “Enhanced Configuration Register” on page 32 for valid AIN and DIN for blo ck erase,

program, or lock-bit configur ation.

7. Write pulse width high (tWPH) is define d from CE X or WE# going high (whichever goes high first) to CEX or WE# going

low (whichever goes low first). Hence, tWPH = tWHWL = tEHEL = tWHEL = tEHWL.

8. For array acces s , t AVQV is required in addition to tWHGL for any accesses after a write.

9. STS timings are based on STS configured in its RY/BY# default mode.

10. VPEN should be held at VPENH until determination of block erase, program, or lock-bit configuration success (SR[5:3,1]

= 0).

8.0 Bus Interface

This sect ion pro vides an overview of Bus operatio ns . The on - c hip Write Stat e M a c hine

(WSM) manages all er ase and progr am algorithms. The system CPU p rovides control of

all in-system read, write, and erase operations through the system bus. All bus cycles

to or from the flash memory conform to standard microprocessor bus cycles. Table 16

summarizes the necessary states of each control signal for different modes of

operations.

Notes:

1. See Table 17 for valid CEx configurations.

2. OE# and WE# should never be asserted simultaneously. If done so, OE# overrides WE#.

3. DQ refers to DQ[7:0] when BYTE# is low an d DQ[ 1 5:0 ] if BYTE# is high.

4. Refer to DC characteristic s. When VPEN ≤ VPENLK, memory contents can be read but not altered.

5. X should be VIL or VIH for the control pins and VPENLK or VPENH for VPEN. For outputs , X shou ld be VOL or VOH.

6. In default mode, STS is VOL when the WSM is executing internal block erase, program, or a lock-bit configuration

algo r ithm. It i s V OH (pulled up by an exter n al pull up resis ta nce ≈ 10k) wh en the WSM i s not bus y, in block erase s u s pend

mode (with programming inactive), program suspend mode, or reset power-down mode.

7. See Section 11.0, “Device Command Codes” on page 47 for valid DIN (user commands) during a Write

operation.

8. Array writes are either program or erase operations.

Numonyx® Embedded Flash Memory (J3 65 nm) Single Bit per Cell (SBC)

8.1 Bus Reads

R eading from flash memory outputs stored information to the processor or chipset, and

does not ch ange any contents. Readin g can be performed an unlimited number of

times. Besides array data, other types of data such as device information and device

status are available from the flash.

To perform a bus read operation, CEx (refer to Table 17 on page 30) and OE # must be

asserted. CEx is the device-s elect control; when active, it enables the flash memory

device. OE# i s t he data-o utpu t contro l; wh en activ e, the addressed f lash me mory d ata

is driven onto the I/O bus. F or all read st ates, WE# and RP# must be de-asserted . See

Section 9.2, “Read Operatio ns ” on page 35.

8.1.1 Asynchronous Page Mode Read

Unlike J3 130nm devices, J3 65 nm SBC device provides Eight-Word Asynchronous

Page mode only. Array data can be sensed up to eight words (16 Bytes) at a time. This

is the default mode on power-up or reset.

On J3 130nm devices, the S et Enhanced Configu ratio n Register command is us ed to

enable Eight-Word Page mode upon power-up or reset, however this has no effect on J3

65 nm SBC devi ce anym ore .

After the initial access delay, the first word out of the page buffer corresponds to the

initial address. Address bits A[3:1] determine which word is output from the page

buffer for a x16 bus width, and A[3:0] determine which byte is output from the page

buffer for a x8 bus width. S ubsequent reads f rom the device come from th e page

buffer. These reads are outp ut on DQ[15:0] f or a x16 bus width and DQ[7 : 0] for a x8

bus width aft er a min imu m delay by changin g A [3:1] or A[3:0].

Data can be read from the page buffer multiple times, and in any order.If address bits

A[MAX:4] change at any time, or if CEx# is toggled, the device will sense and load new

data into th e page bu ffer. A synchro no us Pag e mode is t he def au lt read mod e on p ower -

up or reset.

To perform a P age mode read after an y other operation, the R ead Arr ay command must

be issued to read from the flash array. Asynchronous Page mode read s are permitted in

all blocks and are used to access register information. During register access, only one

word is loaded into the page buffer.

8.1.1.1 Enh an ced Configuration Register

The Enhanced Configuration Register (ECR) is a volatile storage register that when

addressed by the Set ECR command can select between Four- Word Page mode and

Eight-Word Page mode on J3 130nm devices, however this has no effect on J3 65 nm

SBC device.

The EC R is volatile; all bi ts will be r eset to de fault valu es when RP# is deasserted or

power is remo ved fro m the device. To modify ECR settin gs, use the Set ECR command.

The Set EC R co m m and is written al on g with the con figuration re g ister value, wh ich is

placed o n th e lower 16 bits of the addre s s bus A[16:1] . This is fo llowed by a second

write th at conf irms t he operation and again presen ts t he EC R data on the add ress bus .

After exec ut ing this com m a nd , the device r et ur ns to Read Array mode.

The ECR is s ho wn in Table 18. 8-word page mode Command Bus-Cycle is captured in

Table 19 for backward compatibility reasons.

Note: If the 8-word Asynchronous Page mode is used on J3 65 nm SBC, a Clear Status

R egister command must be executed after issuing the Set ECR command.

8.1.2 Output Disable

With CEx asserted, and OE# at a logic-high level (VIH), the device outputs are disabled.

Output signals DQ[15:0] are placed in a high-impedance state.

8.2 Bus Writes

W ritin g or Prog ra mming to the d evice, i s wher e the ho st writ es info rmation o r data in to

the flash device fo r non-volatile sto rage. When the fla s h devic e is pr ogramme d, ‘ones’

are changed to ‘z eros’. ‘Zeros’ ca nn ot be pro gramed back to ‘ones’. To do so, an erase

operatio n must be pe rformed. Writing commands to the Command Use r Interface (CUI)

enables various modes of operat ion, including the following:

• Readin g of array data

• Common Flash Interface (CFI) data

• Identifier codes, inspection, and clearing of the Status Re gister

• Block Erasure, Program, and Lock-bit Configuration (when VPEN = VPENH)

Erasing i s performed on a block basis – all flash cells within a block are erase d together.

Any information or data previously stored in the block will be lost. Erasing is typically

done prior t o programming. Th e Block Erase command requires appropriate command

data and an address within the block t o be erased. The Byte/Word Program comman d

requires the command and address of the location to be written. Set Block Lock-Bit

commands require the command and block within the device to be locked. The Clear

Block Lock-Bits command requires the command and address within the device to be

cleared.

The CUI does not occupy an addressable memory location. It is written when the device

is enabled and WE# is active. The address and data needed to execut e a command are

latched on the rising edge of WE# or CEX (CEX low is de fined as the comb ination of pin s

CE0, CE 1, and CE2 that enable the devic e. CEX high is defined as the combination of

pins CE0, CE1, and CE2 that disable the device. See Table 17 on page 30). Standard

microprocessor write timings are used.

8.3 Standby

CE0, CE1, and CE2 ca n disable the device (see Table 17 on page 30) and place it in

standby mo de. This manipul a tion of CEx substantiall y reduces device pow er

consumption. DQ[15:0] outputs are placed in a high-impedance state independent of

OE#. If deselected during block erase, program, or lock-bit configuration, the WSM

cont inues functioning, and con s um in g a c ti ve power unti l the operation completes.

8.3.1 Reset/Power-Down

RP# at VIL initiates the rese t/ power-dow n mode.

In read modes, RP#-low deselects the memory, places output drivers in a high-

impedance state, and turns off numerous internal circuits. RP# must be held low for a

minimum of tPLPH. Time tPHQV is required after return from reset mode until initial

memory access outputs are valid. After this wake-up interval, normal operation is

restored. The CUI is reset to read array mode and Statu s Register is set to 0080 h.

Durin g Block Erase, Program, or Lock-Bit Config uration modes, RP#-low w ill abo rt the

operation. In default mode, STS tran sitions low and remains low for a maximum time

of tPLPH + tPHRH unt il the res e t operation is complete. Memory contents being altered

are no longer va lid; the dat a ma y be partially corrupted after a program or partially

altered after an erase or lock -bit configuration. Time tPHWL is required after RP# goes to

logic - high (VIH) before another command can be written.

As with any automated device, it is important to assert RP# during system reset. When

the system comes out of reset, it expects to read from the flash memory. Automated

flash memories provide status information when accessed during Block Erase, Program,

or Lock-Bit Configuration modes. If a CPU reset occurs with no flash memory reset,

proper initialization may not occur because the flash memory may be providing status

inform a tion in s tead of ar ra y da ta. Nu monyx F la s h memories a llow pro per initializati on

following a syst em reset thr ou gh the use of th e RP # inp ut. In this app lication, RP# is

controlled by the same RESET# signal that resets the system CPU.

8.4 Device Commands

When VPEN ≤ VPENLK, only read operations from the Status Register, CFI, identifier

codes, or blocks are enabled. Placing VPENH on VPEN addi tionall y enabl es block erase,

program, and lock-bit configuration operations. Device operations are selected b y

writing specific commands to the Command User Interface (CUI). The CUI does not

occupy an addressable memory location. It is the mechanism through which the flash

device is controlled.

A command sequence is issued in two consecutive write cycles - a Setup command

followed by a Confirm command. However, some commands are single-cycle

commands consisting of a setup command only. Generally, commands that alter the

contents of the flash device, such as Progr am or Er ase, require at least two write cy cles

to guard against inadverten t changes to the flash device. Flash commands fall into two

categories: Basic Commands and Extended Commands. Basic commands are

recognized by all Numonyx Flash devices, and are used to perform common flash

operatio ns such as select ing the read mode, progr am ming the arra y, or er asing b locks.

Extended commands are product-dependant; they are used to perform additional

features such as software block locking. Section 11.0, “Device Command Codes” on

page 47 describes all applicable commands on J3 65 nm SBC device.

9.0 Flash Operations

This section describes the operat io nal features of flash memory. Operations are

command-based, wherein command codes are first issued to the device, then the

device performs the desired operation. All command codes are issued to the device

using bus-write cycles (see Chapter 8.0, “Bus Interface”). A complete list of available

command codes can be found in Sect ion 11.0, “Device Command Codes” on page 47 .

9.1 Status Register

The Status R egister (SR) is an 8-bit, read-onl y register that indicates de vice status and

operation errors. To read the Status Register, issue the Re ad Status R egister command.

Subsequent reads output Status Re gister information on DQ[7:0 ], and 00h on

DQ[15:8].

SR status bits are set and cleared by the device. SR error bits are se t by th e device, b ut

must be cleared using the Clear Status R egister command. Up on power-up or exit from

reset, the Status R egister defaults to 80h. Page-mode reads are not supported in this

read mode. Status R egister cont ents are latc hed on the f alling edge of OE# or CE X (CEX

low is defined as the combination of pins CE0, CE1, and CE2 that enable the device.

CEX high is defi ne d as the combi nat ion of pins CE0, CE1 , and CE2 that disable th e

device). OE# must toggle to V IH o r the de vi ce must be di sabled bef ore fu rther re ads to

update the Status R egister latch. The Read Status Register command functions

independently of VPEN voltage.

Numonyx® Embedded Flash Memory (J3 65 nm) Single Bit per Cell (SBC)

9.1.1 Clearing the Status Register

The Status Register (SR) contain Status and error bits which are set by the device. SR

status bits are cleared b y the devic e, however SR e rror bits are cleared b y issuing the

Clear SR command (see Table 21). Resetting the device also clears the SR.

Issuing the Clear SR command places the device in Read SR mode.

Note: Care should be taken to avoid SR ambiguity. If a command sequence error occurs while

in an Erase Suspend condition, the SR will indica te a Command Sequenc e er r or by

setting SR.4 and SR.5. When the erase operation is resumed (and finishes), any errors

that may hav e oc c urred during t he erase operation will be masked by the Command

Sequence error. To avoid this situation, clear the Status Register prior to resuming a

suspen ded eras e operation. Th e Clear SR command functions independent of the

voltage level on VPEN.

9.2 Read Operations

Four types of data can be read from the device: array data, device information, CFI

data, and device statu s . Upon power-up or return fro m reset, the device def aults to

R ead Arr ay mode. To change the device’ s read mode, the appropri ate command must

be issued to the device. Table 22 shows the command codes used to configure the

device for the desired read mode. The followin g sections de scribe each read mode .

9.2.1 Read Array

Upon power-up or return from reset, the devi ce defaults to Read Array mode. Issuin g

the Read Array command places the device in Read A r ray mode. Subse quent r e a d s

output array data on DQ[15:0]. The device remains in Read Array mode until a

different read command is issued, or a program or erase operation is performed, in

which case, the read mode is automatically changed to R ead Status.

To change the dev ice to R e ad Arr ay mo de while it is progra mming or er asing, f irst issue

the Suspend command. After the oper at ion has been suspended, issue the Re ad Array

command. When the program or erase operation is subsequently resumed, the device

will automatically revert back to Read Status mode.

Note: Issuing the Read Array command to the device while it is actively programming or

er as ing causes s ubsequent reads fro m the dev ice to output invalid da ta. Valid array

data is output only after the program or erase operation has finished.

The Read Array command functions independent of the voltage level on VPEN.

9.2.2 Read Status Register

Issuing the Read Status Regi ster command places the device in Read Status Re gister

mode. Subsequent reads output Status Register information on DQ[7:0], and 00h on

DQ[15:8]. T h e device remains in Read Status Register mode un til a different read-

mode command is issued. Performing a program, er ase, or block-lock op eration also

changes the device’s read mode to R ead Status Register mode.

The Status Register is update d on the falling edge of OE# or CEx , wh ichever occurs

last. Statu s R e gist er co nten ts are v ali d onl y when SR.7 = 1. Wh en WSM is acti ve, S R.7

indicates the WSM’s state and SR[6:0] are in high-Z state.

The Read Status Register comman d functions indepe ndent of the voltag e level on

VPEN.

9.2.3 Read Device Information

Issuing the Read Device Information command places the device in Read Device

Information mode. Subsequent reads output device information on DQ[15:0].

The device remains in Read Device Information mode until a different read command is

issued. Also, performing a program, erase , or block-lock operation changes the device

to Read Status Register mode.

The Read De vice Informat ion command functions independent of the voltage level on

VPEN.

9.2.4 CFI Query

The CFI query table contains an assortment of flash product information such as block

size, density, allowable command sets, electrical specifications, and other product

inf orm a tion. The data c on ta ined in this table conforms to the CF I pr ot oc ol.

Issuin g the CFI Query c ommand places the device in CFI Query mode. Subsequent

reads output CFI information on DQ[15:0 ]. The device remains in CFI Query mod e until

a different read command is issued, or a program or erase operation is performed,

which changes the read mode to R ead Status Register mode.

The CFI Query command functions independent of the voltage level on VPEN.

9.3 Programming Operations

All programming oper ations req uire the addr essed block to be unlocked, and a v a lid

VPEN v oltage applied throughout the progr amming operation. Otherwise, the

programming operation will abort, setting the appropri ate Status Register error bit(s).

The following sections describe each programming method.

9.3.1 Single-Word/Byte Programming

Arra y programming is performed by first issuing the Single-Word/Byte P r ogram

command. This is followed by writing the desired data at the desired array address. The

read mode of the devi ce is automat ically change d to R ead Statu s Re gister mode , which

remains in effect until another read-mode command is issued.

208032-03 37

Numonyx® Embedded Flash Memory (J3 65 nm) Single Bit per Cell (SBC)

During pro gramming, STS and the St atus Register indicate a busy statu s (SR. 7 = 0).

Upon completion, STS and the Status Register indicate a ready status (SR.7 = 1). The

Status Register should be checked for any errors (SR.4), then cleared.

Note: Issuing the Read Arr a y command to the device while it is actively programmi ng causes

subsequent reads from the device to output invalid data. V alid array data is output only

after the program operation has finished.

Standby p ower lev els are not be real ized u ntil t he progr ammin g oper ation h as finishe d.

Also, asserting RP# aborts the progr amming o peration, and array contents at the

addressed location are indeterminate . The addressed block should be erased, and the

data re-programmed. If a Single-Word/Byte program is attempted when the

corresponding block lock-bit is set, SR.1 and SR.4 will be set.

9.3.2 Buffered Programming

Buffered programming operation s simultan eously program multiple words/bytes into

the flash memory array, significantly reducing effective w ord-write/byte- write times .

User- data is first written to a write buffer, the n pr ogrammed into the f lash memor y

array in buffer-size increments. For additional details, see the flow chart of the

buffere d-progr amming operation.

Optimal performan c e an d power consumpt ion is realized by alignin g the start address

on 256-Word boun daries (i.e., A[8:1] = 00000000b). Cros s ing a 256-Wo rd boundary

during a buffered programming operation can cause programming time to double.

To perform a buffered programming operation, first issue the Buffered Program setup

command at the desired starting address. The read mode of the device/addressed

partition is a utomatically c ha nged to Read Statu s Reg is ter mode.

Polling SR.7 d etermi nes writ e- buffe r a vailabili ty (0 = no t a vailable , 1 = ava ilable). If

the write buffer is not available, re-issu e the setup command and check SR.7; repeat

until SR.7 = 1.

Note: The devi ce de fault s to ou tput S R data a fter the Bu ffere d Prog ram ming Setup c omma nd

(E8h) is issued. CE# and OE# must be toggled to update Status Register. Don’t issue

the R ead SR comman d (70h), whic h would be interpreted b y the internal state machine

as Buffer Word Count.

Next, issue the word count at the desired starting address. The word count represents

the tot al numbe r of words to be wr itten in to the w rite bu ffer, min us one. T his v alue c an

range from 00 h (one) to a m a ximum of FF h (256). Exceeding the allowa ble ra nge

causes an abort.

Note: The maximum number of bytes in write buffer on CFI region (offset 2Ah, refer Table 41,

“Device Geom etry Defi nition ” on pa g e 6 0) is set to 05h (32 bytes) for backward

compatible reasons. No software change is required on existing applications for both x8

and x16 mode. Applicat ions can optimize the syst em performance us ing the maximum

of 256 buffer size. Please contact your sales representatives for questions.

Followin g the word count, the write buffer is fil led with user - data. Subs eq uent bus-

write cycles prov ide addresses and dat a, up to the word count. All user-data addresse s

must lie between <starting address> and <starting address + word count>, otherwise

the WS M continues to r un as no rmal but, user may advertently c hange the content in

unexpected address locations.

Note: User-data is programmed into the flash array at the address issued when filling the

writ e buffer.

38 208032-03

After all user-data is written into the write buffer, issue the confirm command. If a

command other than the confirm command is issued to the device, a command

sequence error occurs and the operation aborts.

Note: After iss ui ng the confi r m c omman d, write-buffer contents are prog ramme d in to the

flash memory array. The Status Register indicates a busy status (SR.7 = 0) during

array programming.Issuing th e Read Array command to the device whi le it is actively

programming or erasing causes subsequent reads from the device to output invalid

data. Valid arra y data is output only after the progra m or er ase operation has finished.

Upon completion of array programming, the Status Register indicates ready (SR.7 = 1).

A full Status R egister ch eck should be performed to check for an y progr amming errors,

then cleared by using the Clear Status Register command.

Additional buffered progr a mming ope ratio ns can be initiated by issuing another setup

command, and repeating the buf fered progr ammin g bus-cy cle se quence. Howeve r, any

errors in the Status Register must first be cleared before another buffered

programming operation can be initiated.

9.4 Block Erase Operations

Erasing a block change s ‘zeros’ to ‘ones’. To change ones to zeros, a progr am oper ation

must be performed (See Section 9.3, “Programming O p era tions”). Erasing is pe r f ormed

on a block basis - an entire block is erased each time an erase command sequence is

issued. Once a block is fully erased, all addressable locations within that block read as

logical ones (FFFFh for x16 mode, FFh for x8 mode). Only one block -er ase operation

can occur at a time, and is not pe rmitted during a program suspend.

To perform a block-erase operation, issue the Block Erase command sequence at the

desired block address. Table 23 shows the two-cycle Block Erase command sequence.

Note: A block-erase ope ration requ ires the addressed block to be unlocked, and a valid

voltag e applied to VPEN thro ughout the block-er as e operation. Otherwise, the

operation will abort, setting the appropriate Status Register error bit(s).

The Eras e Confirm command latches the address of the bl oc k to be erased. The

addressed blo ck is preconditio ned (programme d to all zeros), erased, and then verified.

The read mode of the device is automatically changed to Read Status Register mode,

and remains in effect until another read-mode command is issued.

During a block-erase operation, ST S and the Status Register indi cate s a busy status

(SR.7 = 0). Upon completion, STS and the Status Register indicates a ready status

(SR.7 = 1). Th e St atus Register sho uld be checked for any errors , then cleared. If any

errors did occur, subsequent erase commands to the device are ignored unless the

Status Register is cleared.

The only valid commands during a block erase operation are Read Array, Read Device

Information, CFI Query, and Erase Suspend. After the block-erase operati on has

completed, any valid command can be issued.

Note: Issuing the Read Array command to the device while it is actively erasi ng causes

subsequent reads from the device to output invalid data. V alid array data is output only

after the block-erase operati o n has finished.

Standb y power levels are not b e realized un til the bloc k-erase operation has finished.

Also, asserting RP# aborts the block-erase operation, and array contents at the

addressed locat ion are indete rmin ate. The addressed block should be erased before

program m ing with in the block is attempted.

9.5 Blank Check

The Bla nk Che c k op e ration determ in es whe ther a spec if ied array block is bla nk (i.e.

completely era sed). W ithou t Blank Check, Block Erase would be the onl y other way to

ensure a block is comple tely erased. Blan k Check is especia lly useful in the case of

erase ope ration interrupted by a power loss event.

Blank Check can apply to only one b lock at a time, and no oper ations other than Status

er ase etc.). Sus pend and resume op eratio ns are not sup ported durin g Blank Check , nor

is Blank Che c k suppo r ted duri ng any s uspended operat ions.

Blank C heck operations are initia ted by wr iting the Bloc k Blank C heck co mmand to the

block address. Next, the Blank Check Confirm command is issued along with the same

block address. When a successful command sequence is entered, the device

automatically enters the Re ad Status State. The WSM then reads the entire specified

block, and determines wh ether an y bit in the blo c k is programmed or over-era sed.

The status register can be examined for Blank Check progress and errors by reading

any address within the block being accessed. During a blank check operation, the

Status Register indicates a busy status (SR.7 = 0). Upon completion, the Status

Regi ster indicates a ready status (SR.7 = 1). The Status Register should be checked for

any errors, and then cleared. If the Blank Check operation fails, which means the block

is not completely erased, the Status Re gister bit SR.5 will be set (“1”). CE# or OE#

toggle (during polling) up dates the Status Register.

The device remains in Status Register Mode until another command is written to the

device. After examinin g the Status Regi ster, it should be cleared by the Clear Status

Blank Check command is complete.

9.6 Suspend and Resume

An er ase or programmin g operation can be suspen ded to perform othe r oper ations, and

then subsequently resumed. Table 24 shows the Suspend and Resume command bus-

cycles.

Note: All erase and programming oper ati ons require the addresse d bl ock to remain u nlocked

with a val id vo ltage applied to VPEN t hroughout t he su spend operation. Otherwise, the

block-erase or programming operation will abort, setting the appropriate Status

R egiste r error bit(s). Also, asserting RP# aborts suspended block-erase and

Numonyx® Embedded Flash Memory (J3 65 nm) Single Bit per Cell (SBC)

Datasheet Jan 2011

40 208032-03

programming operations, rendering array contents at the addressed location(s)

indeterminate.

To suspend an on-going erase or program operation, issue the Suspend command to

any device address. The program or erase oper ation suspends at pre-det ermined point s

during the operation after a delay of tSUSP. Sus pend is achie ved whenS TS (in RY / BY#

mode) goes high, SR[7,6] = 1 (erase-suspend) or SR[7,2] = 1 (program-suspend).

Note: Issuing the Suspend command does not change the read mode of the device. The

device will be in Read Status Register mode from when the erase or program command

was first issued, unless the read mode was changed prior to issuing the Suspend

command.

Not all commands are allowed when the device is suspended. Table 25 shows whi ch

device commands are allowed during Program Suspend or Erase Suspend.

During Suspend, array-read operations are not allowed in blocks being erased or

programmed.

A block-erase under program-suspend is not allowed. However, word-program under

erase-suspend is allowed, and can be suspended. This results in a simultaneous erase-

suspend/ program-suspend condition, indicated by SR[7,6,2] = 1.

To resume a suspended program or erase operation, issue the Resume command to

any device address. The read mode of the device is automatically changed to Read

Status Register. The operation contin ues where it left off, STS (in RY/ BY# mode) goes

low, and t he respective Statu s Register bits are cleared.

When the Resume command is issued during a simultaneous erase-suspend/ program-

suspend condition, the progr amming operation is resumed first. Upon completion of the

program ming operation, the Status Register should be checked for any errors, and

cleared. The resume command must be issued again to complete the erase operation.

Upon completion of the erase operation, the Status Register should be checked for any

errors, and cleared.

9.7 Status Signal

The STATUS (STS) signal can be configured to different states using the STS

Configuration command (Table 26). Once the STS signal has been configured, it

remains in that configuration until another Configuration command is issued or RP# is

asserted low. Initially, the STS s ignal defaults to RY/BY# operat ion wher e RY/BY # low

indicates that the WSM is busy. RY/BY# high indicates that the state machine is ready

for a new operation or suspended. Table 27 displays possible STS configurations.

To reconfigure the ST ATUS (STS) signal to other modes, the Configuration command is

given followed by the desired configur ation code. The three alternate configur ations are

all pulse mode for use as a system interrupt as described in the following paragraphs.

For these configu ratio ns , b it 0 controls Eras e Com p lete inte r r up t pulse, a nd bit 1

contro ls Program Comp lete int er r upt pulse. Suppl ying the 00h confi guration code with

the Configuration command resets the STS signal to the default RY/BY# level mode.

The Configuration command may only be given when the device is not busy or

suspended. Check SR.7 for device status. An inv alid configur at ion code will result in

SR.4 and SR.5 being set.

Note: STS Pulse m od e is no t su p po r te d in the Clear L oc k Bi ts a nd Set Lo c k Bit command s .

9.8 Security and Protection

J3 65 nm SBC device offers both hardware and software security features. Block lock

operati ons, PRs and V PEN allow users to implemen t variou s leve ls of data prote c ti on.

9.8.1 Normal Block Locking

J3 65 nm SBC has the capability of Flexible Block Locking (locked blocks remain locked

upon reset or power cycle): All blocks within the device are in unlocked state when ship

from Numonyx. Blocks can be locked individually by issuing the Set Block Lock Bit

command sequence to any address within a block. Once locked, blocks remain locked

whe n po wer is removed, or when the de vice is rese t .

All locked blocks are unlocked simultaneously by issuing the Clear Block Lock Bits

command sequence to any device address. Locked blocks cannot be er ased or

programmed. Table 28 summarizes the command bus-cycles.

After issuing the Set Block Lock Bit setup command or Clear Block Lock Bits setup

command, the device’s read mode is automatically changed to Read Status Register

mode . After issu ing the con fir m c om m a nd , c om p le tion of the o pe rati on is indica te d by

STS (i n RY/ BY # m ode) goin g high and SR .7 = 1.

Blocks can n ot be l ock ed or unl ock ed w hile p rogrammi ng o r e r asin g, or wh ile the de vi ce

is suspended. Reliable block lock and unlock operations occur only when VCC and VPEN

are valid. When VPEN ≤ VPENLK, block lock-bits cannot be changed.

When the set lock-bi t operation is complete, SR.4 should be checked for any error.

When the clear lock-bit operation is complete, SR.5 should be checked for any error.

Errors bits must be cleared using the Clear Status Register command.

Block lock-bit status can be determined by first issuing the Read Device Information

command, and then reading from <block base address> + 02h. DQ0 indicates the lock

status of the addressed block (0 = unlocked, 1 = locked).

9.8.2 Configurable Block Locking

J3 65 nm SBC devices feature u s er-con figurable bl ock locking. Th is feature c a n be

implemented to protect and/or secure the user’s system. The user can individually set

each block as N on-Volatile Temporar y, No n-V olatile Semi - Permanent or Non- Volatile

P ermanent. For addition al information and collateral, please contact the sales

representative.

9.8.3 Password Access

P assword Access is a security enhancement offered on the J3 65 nm SBC device. This

feature protects information sto red in main-arra y memory blocks by prev enting conte nt

alteration or reads, until a valid 64-bit password is received. Password Access may be

combined with Non-Volatile Protection and/or Volatile Protection to create a multi-

tiere d s olution.

Please contact your Numonyx Sales for further details concerning Password Access.

9.8.4 128-bit OTP Protection Register

J3 65 nm SBC includes a 128-bit Protection Register (PR) that can be used to increase

the security of a system design. For example, the number contained in the PR can be

used to “match” the flash component with other system components such as the CPU

or ASIC, hence preventing device substitution.

The 128-bits of the PR are divided into two 64-bit segments:

• One segment is programmed at the Numonyx factory with a unique unalterable 64-

bit number.

• The other segment is left blank for customer designers to program as desired. Once

the customer segment is programmed, it can be locked to prevent further

programming.

9.8.5 Reading the 128-bit OTP Protection Register

The Protection Register is read in Identification Read mode. The device is switched to

this mode by issuing the Read Id entifier c ommand (0 090h). Once in this mo de, read

cycles from addresses shown in Table 31, “Word-Wide Protection Register Addressing”

or Table 32, “Byt e-Wide Prot ec tion Register Add r es s ing” retrieve the specified

information. To return to Read Array mode, write the R ead Array command (00FFh).

9.8.6 Programming the 128-bit OTP Protection Register

PR bits are pr ogrammed using the t wo - c ycle Program OTP Register command . The 64-

bit numb er is progr a mmed 16 bits at a time for word- wide confi gurat ion and eigh t bits

at a time for by te-wide configurat ion. First write the Prot ec tion Program S etup

command , 00C0h. The next write to the device will latch in address and data and

program the specified location. The allowable addresses are shown in Table 31, “Word-

Wide Protection Register Addressing” on page 45 or Table 32, “Byte-Wide Protection

Numonyx® Embedded Flash Memory (J3 65 nm) Single Bit per Cell (SBC)

Datasheet Jan 2011

44 208032-03

Flowchart” on pa ge 56. Any attempt to address Program OTP Register command

outside the defined PR address space will result in a Status Register error (SR.4 will be

set). Attempting to program a locked PR segment will result in a Status Register error

(SR.4 and SR.1 will be set ).

9.8.7 Locking the 128-bit OTP Protection Register

The user-programmable segment of the PR is lo c kable by program m ing Bit 1 of the

Protection Lock Register (PLR) to 0. Bit 0 of this location is programmed to 0 at the

Numonyx factory to protect the unique device number. Bit 1 is set using the Protection

Program command to program “0xFFFD” to the PLR. After these bits have been

progr a mmed, no further changes can be made to the values s tored in the P r otectio n

Re gis ter error (SR.4 and SR.1 will be s et). The PR lockout state is not reversible.

Note: A0 is not used in x16 mode when accessing the protection register map. See Table 31 for x16 addressin g. In x8 mod e

A0 is used, see Table 32 for x8 addressing.

9.8.8 VPEN Protection

When it’s necessary to protect the entire arr ay, global pro tecti on can be achi eved u sing

a hardware mechanism using VPEN. Whenever a valid voltage is present on VPEN,

block s within the main fla s h array c an be erased or programmed. By grounding V PEN,

For a complete definition on device oper ations refer to Section 8.4, “Devi ce Commands”

on page 33. The list of all applicable commands are included here one more time for

the conven ience.

Note: Some customer applications use illegal or invalid commands (like 0x00) accidentally or

intent ional ly wi th t he devi ce. A n ille gal or in v alid co mmand c aused the device o utpu t to

change to Array R e ad mode on 130nm. On the 65nm device, the output will change to

R ead Status Register mode.

After an ill eg a l or invali d c om m and , s oftware may attem p t to read the de vi c e. If the

illegal command was intentional, software will expect to read array data on 130nm

device, such as 0xFFFF in an unprogrammed location. On the 65nm device, software

may not get the expected array dat a and in stead the stat us register is read.

Please refer to the legal and v alid commands/spec defined in the Datasheet, such as

forr e a d mode, issue 0xFF to Read Ar ray mo d e, 0x90 to Read Sig nature , 0x98 to Read

13.0 Common Flash Interface

The CFI specification outlines device and host system software interrogation handshake

which allows specific vendor-specified software algorithms to be used for entire families

of device s. Th is allows device ind ependent, JEDEC ID-independen t, and forward- and

backward-compatible software support for the specified flash device families. It allows

flash vendors to stan da r dize th eir existing in ter faces f or long-term compatibil ity.

This section defines the data structure or “database” returned by the (CFI) Query

command. System software should parse this structure to gain critical information such

as block size, density, x8/x16, and electrical specifications. Once this information has

been obtained, the software will know w hich comm and s ets to use to enable flash

writes , block erases, and otherwis e c ontrol the flash component. Th e Query is part of

an overall specification for multiple command set and control interface descriptions

called CFI.

13.1 Query Structure Output

The Query “database” allows system software to gain information for controlling the

flash component. This section describes the device’ s CFI-compliant interface that allows

the host system to access Query data.

Query data are always pr es ented on th e lowest-ord er data outputs ( D[ 7: 0]) only. The

numerical offset value is the address relative to the maximum bus width supported by

the device. On this family of devices, the Query table device starting address is a 10h,

which is a word address for x16 devices.

F or a word-w ide (x16) devic e, the first two b ytes of th e Query stru cture, “Q” and “R ” i n

ASCII, appear on the low byte at word addresses 10h and 11h. This CFI-compliant

device outputs 00h data on upper bytes. Thus, the device outputs ASCII “Q” in the low

byte (D[7:0]) and 00h in the high byte (D[15:8]).

At Query addresses containing two or more bytes of information, the least significant

data byte is presente d at the lower address, and the most significant data byte is

presented at the higher address.

In all of the following tables, addresses and data are represented in hexadecimal

notation, so the “h” suffix has been dropped. In additio n, since the u pper by te of word-

wide dev ic es is always “00h,” the leading “00” has been dropp ed from the t a ble

notation an d only th e lower b yte va lue is sh own. Any x1 6 device outputs c a n be

assumed to have 00 h on the upper byt e in this mode.

13.2 Query Structure Overview

The Query comman d c a us es the flash component to dis play th e Common Flash

Interface (CFI) Query structure or “database.” The structure sub-sections and address

locations are summarized below. See AP-646 Common Flash Interface (CFI) and

Command Sets (order number 292204) for a fu ll description of CFI.

The following sections describe the Query structure sub-sections in detail.

x8 mod e N/A (1) N/A(1) 21: 51 “Q”

22: 52 “R”

Note:

1. The system must driv e the lo west order ad dres ses to access a ll the devic e's ar ray data when the devic e is configured in

x8 mode. Therefore, word addressing, wher e th ese lower addresse s are no t tog gled by the system, is "No t Appl i c able"

for x8-configured devi ce s.
