DESCRIPTION

The HY5DU56422D(L)T, HY5DU56822D(L)T and HY5DU561622D(L)T are a 268,435,456-bit CMOS Double Data

Rate(DDR) Synchronous DRAM, ideally suited for the main memory applications which requires large memory density

and high bandwidth.

This Hynix 256Mb DDR SDRAMs offer fully synchronous operations referenced to both rising and falling edges of the

clock. While all addresses and contro l inputs ar e latched on th e rising edges of the CK (falling edg es of the /CK), Data,

Data strobes and W rite data mas ks inputs ar e samp led on both rising and falling edges of it. The data paths are inter-

nally pipelined and 2-bit prefetched to achiev e very high bandwid th. All inp ut and ou tput v o lta ge levels are compatible

with SSTL_2.

PIN DESCRIPTION

PIN TYPE DESCRIPTION

CK, /CK Input Clock: CK and /CK are differential clock inputs. All address and control input signals are

sampled on the crossing of the positive edge of CK and negative edge of /CK. Output

(read) data is referenced to the crossings of CK and /CK (both directions of crossing).

CKE Input

Clock Enable: CKE HIGH activates, and CKE LOW deactiv ates in tern al clock signals, and

device input buffers and output drivers. Taking CKE LOW provides PRECHARGE POWER

DOWN and SELF REFRESH operation (all banks idle), or ACTIVE POWER DOWN (row

ACTIVE in any bank). CKE is synchronous for POWER DOWN entry and exit, and for SELF

REFRESH entry. CKE is asynchronous for SELF REFRESH exit, and for output disable. CKE

must be maintained high throughout READ and WRITE accesses. Input buffers, excluding

CK, /CK and CKE are disabled during POWER DOWN. Input buffers, excluding CKE are dis -

abled during SELF REF RESH. CKE is an SSTL_2 input, but will detect an L VCMOS L OW level

after VDD is applied.

/CS Input Chip Select: Enables or disables all inputs except CK, /CK, CKE, DQS and DM. All com-

mands are masked when CS is registered high. CS provides for external bank selection on

systems with multiple banks. CS is cons idered part of the command code.

BA0, BA1 Input Bank Address Inputs: BA0 and BA1 define to which bank an ACTIVE, Read, Write or PRE-

CHARGE command is being applied.

A0 ~ A12 Input

Address Inputs: Provide the row address for ACTIVE commands, and the column address

and AUTO PRECHARGE bit for READ/WRITE c ommands, to select one location out of the

memory array in the respective bank. A10 is sampled during a precharge command to

determine whether the PRECHARGE applies to one bank (A10 LOW) or all banks (A10

HIGH). If only one bank is to be precharged, the bank is selected by BA0, BA1. The

address inputs also provide the op code duri ng a MODE REGISTER SET command. BA0 and

BA1 define which mode register is loaded during the MODE REGISTER SET command (MRS

or EMRS).

/RAS, /CAS ,/WE Input Command Inputs:/ RAS, /CAS and /WE (along with /CS) define the command being

entered.

(LDM,UDM) Input

Input Data Mask: DM is an input mask signal for write data. Input data is masked when DM

is sampled HIGH along with that input data duri ng a WRITE acces s. DM is sampled on both

edges of DQS. Although DM pins are input only, the DM loading matches the DQ and DQS

loading. For the x16, LDM corresponds to the data on DQ0-Q7; UDM corresponds to the

data on DQ8-Q15.

DQS

(LDQS,UDQS) I/O Data Strobe: Output with read data, input with write data. Edge aligned with read data,

centered in write d a ta. Used to capture write data. For the x16, LDQS corresponds to the

data on DQ0-Q7; UDQS co rresponds to the data on DQ8-Q15.

DQ I/O Data input / output pin: Data bus

VDD/VSS Supply Power supply for internal circuits and input buffers.

VDDQ/VSSQ Supply Power supply for output buffers for noise immunity.

VREF Supply Reference voltage for inputs for SSTL interface.

NC NC No connection.

1. LDM/UDM states are Don’t Care . Refer to below Write Mask Tru th Table.

2. OP Code(Operand Code) consists of A0~A12 and BA0~BA1 used for Mode Register setting during Extended MRS or MRS.

Before entering Mode Register Set mode, all banks must be in a precharge state and MRS command can be issued after tRP

period from Precharge command.

3. If a Read with Autoprecharge command is detected by memory component in CK(n), then there will be no command presented

to activated bank until CK(n+BL /2+ t RP).

4. If a Write with Autoprecharge command is detected by memory component in CK(n), then there will be no command presented

to activated bank until CK(n+BL/2+1 + t W R+tRP). Write Recovery Time (tWR) is needed to guarantee that the last data has be en

completely w r itten.

5. If A10/AP is High when Precharge command being issued, BA0/BA1 are ignored and all banks are selected to be

precharged.

POWER-UP SEQUENCE AND DEVICE INITIALIZATION

DDR SDRAMs must be powered up and initialized in a predefined manner. Operational procedures other than those

specified may result in undefined operation. Power must first be applied to VDD, then to VDDQ, and finally to VREF

(and to the system VTT). VTT must be applied after VD DQ to a voi d device latch-up , which may cause perman ent dam-

age to the device. VREF can be applied anytime after VDDQ, but is expected to be nominally coincident with VTT.

Except for CKE, inputs are not recognized as v alid until after VREF is applied. CKE is an SSTL_2 input, but will detect an

LVCMOS LOW level after VDD is applied. Maintaining an LVCMOS LOW level on CKE during power-up is required to

guarantee that the DQ and DQS outputs will be in the High- Z state, where they will remain until driven in normal oper-

ation (by a read access). After all power supply and reference voltages are stable, and the clock is stable, the DDR

SDRAM requires a 200us delay prior to applying an executable command.

Once the 200us delay has been satisfied, a DESELECT or NOP command should be applied, and CKE should be

brought HIGH. Following the NOP command, a PRECHARGE ALL command should be applied. Next a EXTENDED

MODE REGISTER SET command should be issued for the Extended Mode Register, to enable the DLL, then a MODE

parameters. After the DLL reset, tXSRD(DLL locking time) should be satisfied for read command. After the Mode Reg-

ister set command, a PRECHARGE ALL command should be applied, placing the device in the all banks idle state.

Once in the idle state, two AUTO REFRESH cycles must be performed. Additionally, a MODE REGISTER SET command

for the Mode Register, with the reset DLL bit deactivated low (i.e. to program operating parameters without resetting

the DLL) must be performed. Following these cycles, the DDR SDRAM is read y for normal operation.

1. Apply power - VDD, VDDQ , VTT, VREF in the following power up sequencing and attempt to maintain CKE at LVC-

MOS low state. (All the other input pins may be undefined.)

• VDD and VDDQ are driven from a single power converter output.

• VTT is limited to 1.44V (reflecting VDDQ(max)/2 + 50mV VREF variation + 40mV VTT variation.

• VREF tracks VDDQ/2.

• A minimum resistance of 42 Ohms (22 ohm se ries r esistor + 22 ohm parallel resistor - 5% toler ance) limits the

input current from the VTT supply into any pin.

• If the above criteria cannot be met by the system design, then the following sequencing and voltage relation-

ship must be adhered to during power up.

2. Start clock and maintain stable clock for a minimum of 200usec.

3. After stable power and clock, apply NOP condition and take CKE high.

4. Issue Extended Mode Register Set (EMRS) to enable DLL.

5. Issue Mode Register Set (MRS) to reset DLL and set device to idle state with bit A8=high. (An additional 200

cycles(tXSRD) of clock are required for locking DLL)

6. Issue Precharge commands for all banks of the device.

MODE REGISTER SET (MRS)

The mode register is used to store the various operating modes such as /CAS latency, addressing mode, burst length,

burst type, test mode, DLL reset. The mode register is programed via MRS command. This command is issued by the

low signals of /RAS, /CAS, /CS, /WE and BA0. This command can be issued only when all banks are in idle state and

CKE must be high at least one cycle before the Mode Re gister Set Comm and can be issued. Two cycles are required to

write the data in mode register. During the MRS cycle, any command cannot be issued. Once mode register field is

determined, the information will be held until reset by another MRS command.

BURST DEFINITION

BURST LENGTH & TYPE

Read and write accesses to th e DD R SDRA M are bu rst orie nted, wi th the burst length being programmable. The burst

length determines the maximum number of column locations that can be accessed for a given Read or Write com-

mand. Burst lengths of 2, 4 or 8 locations are available for both the sequential and the interleaved burst types.

Reserved states should not be used, as unknown operation or incompatibility with future versions may result.

When a Read or Write command is issued, a block of columns equal to the burst length is effectively selected. All

accesses for that burst take place within this block, meaning that the burst wraps within the block if a boundary is

reached. The block is uniquely selected by A1-Ai when the burst length is set to two, by A2 -Ai when the burst length

is set to four and by A3 -Ai when the burst length is set to eight (where Ai is the most significant column address bit

for a given configuration). The remaining (least significant) address bit(s) is (are) used to select the starting location

within the block. The programmed burst length applies to both Read and Write bursts.

Accesses within a given burst may be programmed to be either sequential or interleaved; this is referred to as the

burst type and is selected via bit A3. The ordering of accesses within a burst is determined by the burst length, the

burst type and the starting column address, as shown in Burst Definition Table

CAS LATENCY

The Read latency or CAS latency is the delay in clock cycles between the registration of a Read command and the

availability of the first burst of output data. The latency can be programmed 2 or 2.5 clocks for DDR200/266/333 and

3 clocks for DDR400.

If a Read comma nd is registered at clock ed ge n, and the latency is m clocks, the data is av aila ble nominally coinciden t

with clock edge n + m.

Reserved states should not be used as unknown operation or incompatibility with future versions may result.

DLL RESET

The DLL must be enabled f or normal oper ation. DLL enable is requ ired during pow er up initia lizat ion, an d upon ret urn-

ing to normal operation after having disabled the DLL fo r the purpose of debug or evaluation. The DLL is automatically

disabled when entering self refresh operation and is automatically re-enabled upon exit of self refresh operation. Any

time the DLL is enabled, 200 clock cycles must occur to allow time for the internal clock to lock to the externally

applied clock before an any command can be issued.

OUTPUT DRIVER IMPEDANCE CONTROL

The normal drive strength for all outputs is specified to be SSTL_2, Class II. Hynix also supports a half strength driver

option, intended for lighter load and/or point-to-point environments. Selection of the half strength driver option will

reduce the output drive strength by 50% of that of the full strength driver. I-V curves for both the full strength driver

and the half strength driver are included in this document.

EXTENDED MODE REGISTER SET (EMRS)

The Extended Mode Register controls functions beyond those controlled by the Mode Register; these additional func-

tions include DLL enable/disable, output driver strength se lection(optional). These functions are controlled via the bits

shown below. The Extended Mode Register is programmed via the Mode Register Set command (BA0=1 and BA1=0)

and will retain the stored information until it is programmed again or the device loses power.

The Extended Mode Register mus t be loaded when all banks are idle and no bursts are in progress, and the contro ller

must wait the specified time before initiating any subsequent operation. Violating either of these requirements wil

result in unspecified operation.

ABSOLUTE MAXIMUM RATINGS

Note: Operation at above absolute maximum rating can adversely affect device reliability

DC OPERATING CONDITIONS (TA=0 to 70 oC, Voltage referenced to VSS = 0V)

Note:

1. VDDQ must not exceed the level of VDD.

2. VIL (min) is acceptable -1.5V AC pulse width with < 5ns of duration.

3. VREF is expected to be equal to 0.5*VDDQ of the transmitting device, and to track variations in the dc level of the same.

Peak to peak noise on VREF may not exceed ±2% of the DC value.

4. VID is the magnitude of the difference between the input level on CK and the input level on /CK.

5. The ratio of the pullup current to the pulldown current is specified for the same temperature and voltage, over the entire temper-

ature and voltage range, for device drain to source voltages from 0.25V to 1.0V. For a given output, it represents the maximum

difference between pullup and pulldown drivers due to process variation. The full variation in the ratio of the maximum to mini-

mum pullup and pulldown current will not exceed 1/7 for device drain to source voltages from 0.1 to 1.0.

6. VIN=0 to VDD, All other pins ar e no t tested under VIN =0V.

7. DQs are disabled, VOUT =0 to VDDQ

but the related specifications and device operation are guaranteed for the full voltage range specified.

3. Below figure represents the timing reference load used in defining the relevant timing parameters of the part. It is not intended to

be either a precise representation of the typical system environm ent nor a depiction o f the actual load p resented by a producti on

tester. System designers will use IBIS or other simulation tools to correlate the timing reference load to a system environment.

Manufactur ers will correlat e to their product ion test condition s (generall y a coaxial tr ansmission line terminated at t he tester elec-

4. AC timing and IDD tests may use a VIL to VIHswing of up to 1.5 V in the test environment, but input timing is still referenced to

VREF (or to the crossing point for CK, /CK), and parameter specifications are guaranteed for the specified ac input levels under

normal use conditions. The minimum slew rate for the input signals is 1 V/ns in the range between VIL(ac) and VIH(ac).

5. The ac and dc input level specifications are as defined in the SSTL_2 Standard (i.e., the receiver will effectively switch as a result

of the signal crossing the ac input level and will remain in that state as long as the signal does not ring back above (below) the

dc input LOW (HIGH) level.

6. Inputs are not recognized as valid until VREF stabilizes. Exception: during the period before VREF stabilizes, CKE < 0.2VDDQ is

recognized as LOW.

7. The CK, /CK input reference le vel (for timing referenced to CK , /CK) is the point at which CK and /CK cros s; the input reference

level for signals other than CK, /CK is VREF.

8. The output timing reference voltage level is VTT.

9. Oper at ion or timin g that i s not s pecif ied is illegal and after such an ev ent, in order to guarantee proper operation, the DRAM must

be powered down and then restarted through the specified initialization sequence before normal operation ca n continue .

10. tHZ and tLZ tr ansi tion s oc cur in the sam e access time windows as valid data tr ans itio ns. Thes e parameters are not r ef er ence d t o

a specific voltage level but specify when the device output is no longer driving (HZ), or begins driving (LZ).

11. The maximum limit for this parameter is not a device limit. The device wil l operate with a greater value for this parameter, but

system performance (bus turnaround) will degrade accordingly.

12. The specific requirement is that DQS be valid (HIGH, LOW, or at some point on a valid transition) on or before this CK edge. A

valid transition is defined as monot onic and meeting the input slew rate specifications of the device. When no writes were previ-

ously in progress on the bus, DQ S will be transitio n ing from High-Z to logic LOW. If a previous write was in prog ress, DQS could

be HIGH, LOW, or transitioning f rom HIGH to LOW at this time, depending on tDQSS.

13. A maximum of eight AUTO REFRESH commands can be posted to any given DDR SDRAM device.

14. For command/address input slew rate ≥1.0 V/ns.

15. For command/address input slew rate ≥0.5 V/ns and ＜1.0 V/ns

16. For CK & /CK slew rate ≥1.0 V/ns (single-ended)

17. These parameters guarantee device timing, but they are not necessarily tes ted on each device.

They may be guaranteed by device design or tester correlation.

18. Slew Rate is measured between VOH(ac) and VOL(ac).

19. Min (tCL, tCH) r ef ers to th e smaller of the ac tual clo ck l ow time an d the actu al cl ock hi gh t ime as pr ov ided t o the dev ice (i.e. this

value can be greater than the minimum specification limits for tCL and tCH).

For example, tCL and tCH are = 50% of the period, less the half period jitter (tJIT(HP)) of the clock source, and less the half

period jitter due to crosst alk (t JIT(crosstalk)) into the clock traces.

20.tQH = tHP - tQHS, where:

tHP = minimum half clock period for any given cycle and is defined by clock high or clock low (tCH, tCL). tQHS accounts for 1) The

pulse duration distort ion of on-chip clock circuit s; and 2) The worst case pus h-- out of DQS on one transition followed by the

worst case pull--in of DQ on the next transition, both of which are, separately, due to data pin skew and output pattern effects,

and p-channel to n-channel variation of the output drivers.

21. tDQSQ:

Consists of data pi n skew an d output pattern effects, and p-channel to n-channel variation of the output drivers for any given

cycle.

22. tDAL = (tWR/tCK) + (tRP/tCK)

For each of the terms above, if not already an integer, round to the next highest integer.

Example: For DDR266B at CL=2.5 and tCK=7.5 ns

tDAL = ((15 ns / 7.5 ns) + (20 ns / 7. 5 ns)) clocks

= ((2) + (3)) clocks

= 5 clocks

23. In all circu m stances, tXSNR can be sati sfied using

tXSNR = tRFCmin + 1*tCK

24. The only time that the clock frequency is allowed to change is during self-refresh mode.

25. If refresh timing or tDS/tDH is violated, data corruption may occur and the data must be re- w rit ten with v ali d data bef or e a v alid

READ can be executed.

Note:

1. Pullup slew rate is characterized under the te st conditions as shown in bel ow Figure.

2. Pulldown slew rate is measured under the test conditions shown in below Figure.

3. Pullup slew rate is measured between (VDDQ/2 - 320 mV ±250mV)

Pulldown slew rate is measured between (VDDQ/2 + 320mV ±250mV)

Pullup and Pu lldown slew r ate con ditions are to be met fo r any pat tern of d ata, includi ng all outp uts switch ing and on ly one output

switching.

Example: For typical slew, DQ0 is switching

For minimum slew rate, all DQ bits are switching worst case pattern

For maximum slew rate, only one DQ is switching from either high to low, or low to high.

The remaining DQ bits remain the same as for previous state.

4. Evaluation conditions

Typical: 25 oC (Ambient), VDDQ = nominal, typical process

Minimum: 70 oC (Ambient), VDDQ = minimum, slow-slow process

Maximum: 0 oC (Ambient), VDDQ = Maximum, fast-fast process

5. The ratio of pullup sl ew r a te to pulldown slew r ate is specified for the same temper ature an d vo ltage, ov er th e entir e temperature

and voltage range. F or a giv en output, it r epresents th e maximum differ ence between pullup and pulldown drivers due to process

variation.

6. Verified under typical conditions for qualification purposes.

7. TSOP-II package devices only.

8. Only intended for operation up to 256 Mbps per pin.

9. A derating factor will be used to increase tIS and tIH in the case where the input slew rate is below 0.5 V/ns as shown in Table b.

The Input slew rate is based on the lesser of the slew rates determined by either VIH(AC) to VIL(AC) or VIH(DC) to VIL(DC), sim-

ilarly for rising transitions.

10. A derating factor will be used to increase tDS and tDH in the case where DQ, DM, and DQS slew rates differ, as shown in Tables c

& d. Input sl ew r ate is base d on the larger o f AC -A C delta rise, f all r ate and D C -DC delta rise, f all r ate. Input slew r ate is bas ed on

the lesser of the slew rates determined by either VIH(AC) to VIL(AC) or VIH(DC) to VIL(DC), similarly for rising transitions. The

delta rise/fall rate is calculated as:

{1/(Slew Rate1)} - {1/(slew Rate2)}

For example:

If Slew Rate 1 is 0.5 V/ns and Slew Rate 2 is 0.4 V/ns, then the delta rise, fall rate is -0.5 ns/V. Using the table given, this would

result in the need for an increase in tDS and tDH of 100ps.

11. Table c is used to increase tDS and tDH in the case where the I/O slew rate is below 0.5 V/ns. The I/O slew rate is based on the

lesser of the AC- AC slew r ate and the DC -DC slew rate. The input slew r ate is based on the lesser of the slew rates determined by

either VIH(ac) to VIL(AC) or VIH(DC) to VIL(DC), and similarly for rising transitions.

12. DQS, DM, an d D Q input slew rate is specified to prevent double clocking of data a n d preserve se tup and hold ti mes. Signal tran-

sitions through the DC region must be monot onic.
