Offered in 64Mx8bit or 32Mx16bit, the K9K12XXX0C is 512M bit with spare 16M bit capacity. The device is offered in 1.8V, 2.65V,
3.3V Vcc. Its NAND cell provides the most cost-effective solutIon for the solid state mass storage market. A program operation can
be performed in typical 200µs on the 528-byte(X8 device) or 264-word(X16 device) page and an erase operation can be performed
in typical 2ms on a 16K-byte(X8 device) or 8K-word(X16 device) block. Data in the page can be read out at 50ns(K9K1216Q0C :
60ns) cycle time per byte (X8 device) or word(X16 device). The I/O pins serve as the ports for address and data input/output as well
as command input. The on-chip write control automates all program and erase functions including pulse repetition, where required ,
and internal verification and margining of data. Even the write-intensive systems can take advantage of the K9K12XXX0Cs extended
reliability of 100K program/erase cycles by providing ECC(Error Correcting Code) with real time mapping-out algorithm.
The K9K12XXX0C is an optimum solution for large nonvolatile storage applications such as solid state file storage and other portable
applications requiring non-volatility.

PIN DESCRIPTION
NOTE : Connect all VCC and VSS pins of each device to common power supply outputs.
Do not leave VCC or VSS disconnected.
Pin Name Pin Function
I/O0 ~ I/O7
(K9K1208X0C)
I/O0 ~ I/O15
(K9K1216X0C)
DATA INPUTS/OUTPUTS
The I/O pins are used to input command, address and data, and to output data during read operations. The
I/O pins float to high-z when the chip is deselected or when the outputs are disabled.
I/O8 ~ I/O15 are used only in X16 organization device. Since command input and address input are x8 oper-
ation, I/O8 ~ I/O15 are not used to input command & address. I/O8 ~ I/O15 are used only for data input and
output.
CLE COMMAND LATCH ENABLE
The CLE input controls the activating path for commands sent to the command register. When active high,
commands are latched into the command register through the I/O ports on the rising edge of the WE signal.
ALE ADDRESS LATCH ENABLE
The ALE input controls the activating path for address to the internal address registers. Addresses are
latched on the rising edge of WE with ALE high.
CE
CHIP ENABLE
The CE input is the device selection control. When the device is in the Busy state, CE high is ignored, and
the device does not return to standby mode in program or erase operation. Regarding CE control during
read operation, refer to ’Page read’ section of Device operation .
RE READ ENABLE
The RE input is the serial data-out control, and when active drives the data onto the I/O bus. Data is valid
tREA after the falling edge of RE which also increments the internal column address counter by one.
WE WRITE ENABLE
The WE input controls writes to the I/O port. Commands, address and data are latched on the rising edge of
the WE pulse.
WP
WRITE PROTECT
The WP pin provides inadvertent write/erase protection during power tra nsitions. The internal high voltage
generator is reset when the WP pin is active low. When LOCKPRE is a logic high and WP is a logic low, the
all blocks go to lock state.
R/B
READY/BUSY OUTPUT
The R/B output indicates the status of the device operation. When low, it indicates that a program, erase or
random read operation is in process and returns to high state upon completion. It is an open drain output and
does not float to high-z condition when the chip is deselected or when outputs are disabled.
VccQOUTPUT BUFFER POWER
VccQ is the power supply for Output Buffer.
VccQ is internally connected to Vcc, thus should be biased to Vcc.
Vcc POWER
VCC is the power supply for device.
Vss GROUND
N.C NO CONNECTION
Lead is not internally connected.
DNU DO NOT USE
Leave it disconnected
LOCKPRE
LOCK MECHANISM & POWER-ON AUTO-READ ENABLE
To Enable and disable the Lock mechanism and Power On Auto Read. When LOCKPRE is a logic high,
Block Lock mode and Power-On Auto-Read mode are enabled, and when LOCKPRE is a logic low, Block
Lock mode and Power-On Auto-Read mode are disabled. Power-On Auto-Read mode is available only on
3.3V device(K9K12XXU0C)
Not using LOCK MECHANISM & POWER-ON AUTO-READ, connect it Vss or leave it N.C

PRODUCT INTRODUCTION
The K9K12XXX0C is a 528Mbit(553,648,218 bit) memory organized as 131,072 rows(pages) by 528(X8 device) or 264(X16 device)
columns. Spare eight columns are located from column address of 512~527(X8 device) or 256~263(X16 device). A 528-byte(X8
device) or 264-word(X16 device) data register is connected to memory cell arrays accommodating data transfer between the I/O buff-
ers and memory during page read and page program operations. The memory array is made up of 16 cells that are serially con-
nected to form a NAND structure. Each of the 16 cells resides in a different page. A block consists of two NAND structured strings. A
NAND structure consists of 16 cells. Total 135168 NAND cells reside in a block. The array organization is shown in Figure 2-1,2-2.
The program and read operations are executed on a page basis, while the erase operation is executed on a block basis. The memory
array consists of 4096 separately erasable 16K-Byte(X8 device) or 8K-Word(X16 device) blocks. It indicates that the bit by bit erase
operation is prohibited on the K9K12XXX0C.
The K9K12XXX0C has addresses multiplexed into 8 I/Os(X16 device case : lower 8 I/Os). K9K1216X0C allows sixteen bit wide data
transport into and out of page registers. This scheme dramatically reduces pin counts while providing high performance and allows
systems upgrades to future densities by maintaining consistency in system board design. Command, address and data are all written
through I/Os by bringing WE to low while CE is low. Data is latched on the rising edge of WE. Command Latch Enable(CLE) and
Address Latch Enable(ALE) are used to multiplex command and address respectively, via the I/O pins. Some commands require one
bus cycle. For example, Reset command, Read command, Status Read command, etc require just one cycle bus. Some other com-
mands like Page Program and Copy-back Program and Block Erase, require three cycles: one cycle for setup and the other cycle for
execution. The 32M-byte(X8 device) or 16M-word(X16 device) physical space requires 25 addresses(X8 device) or 24
addresses(X16 device), thereby requiring four cycles for word-level addressing: column address, low row address and high row
address, in that order. Page Read and Page Program need the same four address cycles following the required command input. In
Block Erase operation, however, only the three row address cycles are used. Device operations are selected by writing specific com-
mands into the command register. Table 1 defines the specific commands of the K9K12XXX0C.
The device includes one block sized OTP(One Time Programmable), which can be used to increase system security or to provide
identification capabilities. Detailed information can be obtained by contact with Samsung.

NAND Flash Technical Notes
Identifying Invalid Block(s)
Invalid Block(s)
Invalid blocks are defined as blocks that contain one or more invalid bits whose reliability is not guaranteed by Samsung. The infor-
mation regarding the invalid block(s) is so called as the invalid block information. Devices with invalid block(s) have the same quality
level as devices with all valid blocks and have the same AC and DC characteristics. An invalid block(s) does not affect the perfor-
mance of valid block(s) because it is isolated from the bit line and the common source line by a select transistor. The system design
must be able to mask out the invalid block(s) via address mapping. The 1st block, which is placed on 00h block address, is guaran-
teed to be a valid block, does not require Error Correction up to 1K program/erase cycles.
All device locations are erased(FFh) except locations where the invalid block(s) information is written prior to shipping. The invalid
block(s) status is defined by the 6th byte(X8 device) or 1st word(X16 device) in the spare area. Samsung makes sure that either the
1st or 2nd page of every invalid block has non-FFh(X8 device) or non-FFFFh(X16 device) data at the column address of 517(X8
device) or 256 and 261(X16 device). Since the invalid block information is also erasable in most cases, it is impossible to recover the
information once it has been erased. Therefore, the system must be able to recognize the invalid block(s) based on the original
invalid block information and create the invalid block table via the following suggested flow chart(Figure 3). Any intentional erasure of
the original invalid block information is prohibited.
*Check "FFh" at the column address

Error in write or read operation
Within its life time, the additional invalid blocks may develop with NAND Flash memory. Refer to the qualification report for the actual
data.The following possible failure modes should be considered to implement a highly reliable system. In the case of status read fail-
ure after erase or program, block replacement should be done. Because program status fail during a page program does not affect
the data of the other pages in the same block, block replacement can be executed with a page-sized buffer by finding an erased
empty block and reprogramming the current target data and copying the rest of the replaced block. To improve the efficiency of mem-
ory space, it is recommended that the read or verification failure due to single bit error be reclaimed by ECC without any block
replacement. The said additional block failure rate does not include those reclaimed blocks.

Samsung NAND Flash has three address pointer commands as a substitute for the two most significant column addresses. ’00h’
command sets the pointer to ’A’ area(0~255byte), ’01h’ command sets the pointer to ’B’ area(256~511byte), and ’50h’ command sets
the pointer to ’C’ area(512~527byte). With these commands, the starting column address can be set to any of a whole
page(0~527byte). ’00h’ or ’50h’ is sustained until another address pointer command is inputted. ’01h’ command, however, is effective
only for one operation. After any operation of Read, Program, Erase, Reset, Power_Up is executed once with ’01h’ command, the
address pointer returns to ’A’ area by itself. To program data starting from ’A’ or ’C’ area, ’00h’ or ’50h’ command must be inputted
before ’80h’ command is written. A complete read operation prior to ’80h’ command is not necessary. To program data starting from
’B’ area, ’01h’ command must be inputted right before ’80h’ command is written.

starting column address can be set to any of a whole page(0~263word). ’00h’ or ’50h’ is sustained until another address pointer com-
mand is inputted. To program data starting from ’A’ or ’B’ area, ’00h’ or ’50h’ command must be inputted before ’80h’ command is

For an easier system interface, CE may be inactive during the data-loading or sequential data-reading as shown below. The internal
528byte(x8 device), 264word(x16 device) page registers are utilized as seperate buffers for this operation and the system design
gets more flexible. In addition, for voice or audio applications which use slow cycle time on the order of u-seconds, de-activating CE

DEVICE OPERATION
PAGE READ
Upon initial device power up, the device defaults to Read1 mode. This operation is also initiated by writing 00h to the command regis-
ter along with three address cycles. Once the command is latched, it does not need to be written for the following page read opera-
tion. Two types of operations are available : random read, serial page read.
The random read mode is enabled when the page address is changed. The 528 bytes(X8 device) or 264 words(X16 device) of data
within the selected page are transferred to the data registers in less than 10µs(tR). The system controller can detect the completion of
this data transfer(tR) by analyzing the output of R/B pin. Once the data in a page is loaded into the registers, they may be read out in
50ns cycle time by sequentially pulsing RE. High to low transitions of the RE clock output the data starting from the selected column
address up to the last column address[column 511/ 527(X8 device) 255 /263(X16 device) depending on the state of GND input pin].
The way the Read1 and Read2 commands work is like a pointer set to either the main area or the spare area. The spare area of 512
~527 bytes(X8 device) or 256~263 words(X16 device) may be selectively accessed by writing the Read2 command with GND input
pin low. Addresses A0~A3(X8 device) or A0~A2(X16 device) set the starting address of the spare area while addresses A4~A7 are
ignored in X8 device case or A3~A7 must be "L" in X16 device case. The Read1 command is needed to move the pointer back to the
main area. Figures 8, 9 show typical sequence and timings for each read operation.

PAGE PROGRAM
The device is programmed basically on a page basis, but it does allow multiple partial page programing of a byte/word or consecutive
bytes/words up to 528(X8 device) or 264(X16 device), in a single page program cycle. The number of consecutive partial page program-
ming operation within the same page without an intervening erase operation should not exceed 2 for main array and 3 for spare array.
The addressing may be done in any random order in a block. A page program cycle consists of a serial data loading period in which
up to 528 bytes(X8 device) or 264 words(X16 device) of data may be loaded into the page register, followed by a non-volatile program-
ming period where the loaded data is programmed into the appropriate cell. About the pointer operation, please refer to the attached
technical notes.
The serial data loading period begins by inputting the Serial Data Input command(80h), followed by the three cycle address input and
then serial data loading. The words other than those to be programmed do not need to be loaded.The Page Program confirm com-
mand(10h) initiates the programming process. Writing 10h alone without previously entering the serial data will not initiate the pro-
gramming process. The internal write controller automatically executes the algorithms and timings necessary for program and verify,
thereby freeing the system controller for other tasks. Once the program process starts, the Read Status Register command may be
entered, with RE and CE low, to read the status register. The system controller can detect the completion of a program cycle by mon-
itoring the R/B output, or the Status bit(I/O 6) of the Status Register. Only the Read Status command and Reset command are valid
while programming is in progress. When the Page Program is complete, the Write Status Bit(I/O 0) may be checked(Figure 10). The
internal write verify detects only errors for "1"s that are not successfully programmed to "0"s. The command register remains in Read
Status command mode until another valid command is written to the command register.

COPY-BACK PROGRAM
The copy-back program is configured to quickly and efficiently rewrite data stored in one page within the array to another page within
the same array without utilizing an external memory. Since the time-consuming sequently-reading and its re-loading cycles are
removed, the system performance is improved. The benefit is especially obvious when a portion of a block is updated and the rest of
the block also need to be copied to the newly assigned free block. The operation for performing a copy-back is a sequential execution
of page-read without burst-reading cycle and copying-program with the address of destination page. A normal read operation with
"00h" command with the address of the source page moves the whole 528bytes/264words(X8 device:528bytes, X16
device:264words) data into the internal buffer. As soon as the Flash returns to Ready state, copy-back programming command "8Ah"
may be given with three address cycles of target page followed. The data stored in the internal buffer is then programmed directly into
the memory cells of the destination page. Once the Copy-Back Program is finished, any additional partial page programming into the
copied pages is prohibited before erase. Since the memory array is internally partitioned into four different planes, copy-back program
is allowed only within the same memory plane. Thus, A14 and A25, the plane address, of source and destination page address must
be the same."When there is a program-failure at Copy-Back operation, error is reported by pass/fail status. But if the soure
page has a bit error for charge loss, accumulated copy-back operations could also accumulate bit errors. For this reason,
two bit ECC is recommended for copy-back operation."

Figure 12. Block Erase Operation
BLOCK ERASE
The Erase operation is done on a block basis. Block address loading is accomplished in three cycles initiated by an Erase Setup com-
mand(60h). Only address A14 to A25 is valid while A9 to A13 is ignored. The Erase Confirm command(D0h) following the block address
loading initiates the internal erasing process. This two-step sequence of setup followed by execution command ensures that memory
contents are not accidentally erased due to external noise conditions.
At the rising edge of WE after the erase confirm command input, the internal write controller handles erase and erase-verify. When
the erase operation is completed, the Write Status Bit(I/O 0) may be checked. Figure 12 details the sequence.

READ STATUS
The device contains a Status Register which may be read to find out whether program or erase operation is completed, and whether
the program or erase operation is completed successfully. After writing 70h command to the command register, a read cycle outputs
the content of the Status Register to the I/O pins on the falling edge of CE or RE, whichever occurs last. This two line control allows
the system to poll the progress of each device in multiple memory connections even when R/B pins are common-wired. RE or CE
does not need to be toggled for updated status. Refer to table 4 for specific Status Register definitions. The command register
remains in Status Read mode until further commands are issued to it. Therefore, if the status register is read during a random read
cycle, a read command(00h or 50h) should be given before serial access cycle.

READ ID
The device contains a product identification mode, initiated by writing 90h to the command register, followed by an address input of
00h. Two read cycles sequentially output the manufacture code(ECh), and the device code respectively. The command register
remains in Read ID mode until further commands are issued to it. Figure 13 shows the operation sequence.

RESET
The device offers a reset feature, executed by writing FFh to the command register. When the device is in Busy state during random
read, program or erase mode, the reset operation will abort these operations. The contents of memory cells being altered are no
longer valid, as the data will be partially programmed or erased. The command register is cleared to wait for the next command, and
the Status Register is cleared to value C0h when WP is high. Refer to table 5 for device status after reset operation. If the device is
already in reset state a new reset command will not be accepted by the command register. The R/B pin transitions to low for tRST
after the Reset command is written. Refer to Figure 14 below.

Block Lock mode is enabled while LOCKPRE pin state is high, which is to offer protection features for NAND Flash data. The Block
Lock mode is divided into Unlock, Lock, Lock-tight operation. Consecutive blocks protects data by allowing those blocks to be locked
or lock-tighten with no latency. This block lock scheme offers two levels of protection. The first allows software control(command input
method) of block locking that is useful for frequently changed data blocks, while the second requires hardware control(WP low pulse
input method) before locking can be changed that is useful for protecting infrequently changed code blocks.
The followings summarized the locking functionality.
- All blocks are in a locked state on power-up. Unlock sequence can unlock the locked blocks.
- The Lock-tight command locks blocks and prevents from being unlocked.
And Lock-tight state can be returned to lock state only by Hardware control(WP low pulse input).
Block Lock Mode
- Command Sequence: Lock block Command(2Ah)
- All blocks default to locked by power-up and Hardware control(WP low pulse input)
- Partial block lock is not available; Lock block operation is based on all block unit
- Unlocked blocks can be locked by using the Lock block command, and a lock block’s status can be changed to unlock or lock-tight
using the appropriate commands

Block Lock Status can be read on a block basis, which may be read to find out whether designated block is available to be pro-
grammed or erased. After writing 7Ah command to the command register. and block address to be checked, a read cycle outputs the
content of the Block Lock Status Register to the I/O pins on the falling edge of CE or RE, whichever occurs last. This two line control
allows the system to poll the progress of each device in multiple memory connections even when R/B pins are common-wired. RE or
CE does not need to be toggled for updated status. Blcok Lock Status Read is prohibited while the device is busy state.
Refer to table 6 for specific Status Register definitions. The command register remains in Block Lock Status Read mode until further
commands are issued to it. In high state of LOCKPRE pin, write protection status can be checked by Block Lock Status
Read(7Ah) while in low state by Status Read(70h).

Power-On Auto-Read
The device is designed to offer automatic reading of the first page without command and address input sequence during power-on.
An internal voltage detector enables auto-page read functions when Vcc reaches about 1.8V. LOCKPRE pin controls activation of
auto- page read function. Auto-page read function is enabled only when LOCKPRE pin is logic high state. Serial access may be done
after power-on without latency. Power-On Auto Read mode is available only on 3.3V device(K9K12XXU0C).

READY/BUSY
The device has a R/B output that provides a hardware method of indicating the completion of a page program, erase and random
read completion. The R/B pin is normally high but transitions to low after program or erase command is written to the command regis-
ter or random read is started after address loading. It returns to high when the internal controller has finished the operation. The pin is
an open-drain driver thereby allowing two or more R/B outputs to be Or-tied. Because pull-up resistor value is related to tr(R/B) and
current drain during busy(ibusy) , an appropriate value can be obtained with the following reference chart(Fig 17). Its value can be
determined by the following guidance.

The device is designed to offer protection from any involuntary program/erase during power-transitions. An internal voltage detector
disables all functions whenever Vcc is below about 1.1V(1.8V device), 1.8V(2.65V device), 2V(3.3V device). WP pin provides hard-
ware protection and is recommended to be kept at VIL during power-up and power-down and recovery time of minimum 10µs is
required before internal circuit gets ready for any command sequences as shown in Figure 18. The two step command sequence for
program/erase provides additional software protection.
