PRELIMINARY
DESCRIPTION
The Hynix HY5DU56422, HY5DU56822 and HY5DU561622 are a 268,435,456-bit CMOS Double Data Rate(DDR) Syn-
chronous DRAM, ideally suited for the main memory applications which requires large memory density and high band-
width.
The Hynix 256Mb DDR SDRAMs offer fully synchronous operations referenced to both rising and falling edges of the
clock. While all addresses and control inputs are latched on the rising edges of the CK (falling edges of the /CK), Data,
Data strobes and Write data masks inputs are sampled on both rising and falling edges of it. The data paths are inter-
nally pipelined and 2-bit prefetched to achieve very high bandwidth. All input and output voltage levels are compatible
with SSTL_2.

PIN DESCRIPTION

TYPE
DESCRIPTION
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).
CK, /CK
Input
Clock Enable: CKE HIGH activates, and CKE LOW deactivates internal 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
disabled during SELF REFRESH. CKE is an SSTL_2 input, but will detect an LVCMOS LOW
level after Vdd is applied.
CKE
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 considered part of the command code.
/CS
Input
Input
Bank Address Inputs: BA0 and BA1 define to which bank an ACTIVE, Read, Write or PRE-
CHARGE command is being applied.
BA0, BA1
Address Inputs: Provide the row address for ACTIVE commands, and the column address
and AUTO PRECHARGE bit for READ/WRITE commands, 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 during a MODE REGISTER SET command. BA0
and BA1 define which mode register is loaded during the MODE REGISTER SET command
(MRS or EMRS).
A0 ~ A12
Input
Command Inputs: /RAS, /CAS and /WE (along with /CS) define the command being
entered.
/RAS, /CAS, /WE
Input
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 during a WRITE access. 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 corre-
sponds to the data on DQ8-Q15.
DM
(LDM, UDM)
Data Strobe: Output with read data, input with write data. Edge aligned with read data,
centered in write data. Used to capture write data. For the x16, LDQS corresponds to the
data on DQ0-Q7; UDQS corresponds to the data on DQ8-Q15.

( H=Logic High Level, L=Logic Low Level, X=Don’t Care, V=Valid Data Input, OP Code=Operand Code, NOP=No Operation )
Note :
1. LDM/UDM states are Don’t Care. Refer to below Write Mask Truth Table.
2. OP Code(Operand Code) consists of A0~A11 and BA0~BA1 used for Mode Register setting duing 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 Prechagre 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+tRP).
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+tDPL+tRP). Last Data-In to Prechage delay(tDPL) which is also called Write Recovery Time
(tWR) is needed to guarantee that the last data has been completely written.
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. Except for CKE, inputs are not recognized as valid 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 operation (by a read access). After all power supply and reference volt-
ages are stable, and the clock is stable, the DDR SDRAM requires a 200us delay prior to applying an executable com-
mand.
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
REGISTER SET command should be issued for the Mode Register, to reset the DLL, and to program the operating
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 low (i.e. to program operating parameters without resetting the DLL)
must be performed. Following these cycles, the DDR SDRAM is ready 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.
No power sequencing is specified during power up or power down given the following cirteria :
• 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 series resistor + 22 ohm parallel resistor - 5% tolerance) 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 relationship must
be adhered to during power up :
Voltage description

< VDD + 0.3V
VDDQ
VTT
After or with VDD

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 Register Set Command 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 resetted by another MRS command.

BURST LENGTH & TYPE
Read and write accesses to the DDR SDRAM are burst oriented, with 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 A 2 -Ai when the burst length
is set to four and by A 3 -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 Definitionon Table

HY5DU561622CT-D4/D43
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 is 3 clocks.
If a Read command is registered at clock edge n, and the latency is m clocks, the data is available nominally coincident
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 for normal operation. DLL enable is required during power up initialization, and upon return-
ing to normal operation after having disabled the DLL for 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 selection(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 must be loaded when all banks are idle and no bursts are in progress, and the controller
must wait the specified time before initiating any subsequent operation. Violating either of these requirements will
result in unspecified operation.

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

Note :
1. This calculation accounts for tDQSQ(max), the pulse width distortion of on-chip circuit and jitter.
2. Data sampled at the rising edges of the clock : A0~A12, BA0~BA1, CKE, /CS, /RAS, /CAS, /WE.
3. For command/address input slew rate>=1.0V/ns
4. For command/address input slew rate>=0.5V/ns and <1.0V/ns
This derating table is used to increase tIS/tIH in case where the input slew-rate is below 0.5V/ns.

5. CK, /CK slew rates are>=1.0V/ns, ie, >= 2.0V/ns differential
6. These parameters guarantee device timing, but they are not necessarily tested on each device, and they may be guaranteed by
design or tester correlation.
7. Data latched at both rising and falling edges of Data Strobes(LDQS/UDQS) : DQ, LDM/UDM.
8. Minimum of 200 cycles of stable input clocks after Self Refresh Exit command, where CKE is held high, is required to complete
Self Refresh Exit and lock the internal DLL circuit of DDR SDRAM.
9. Min (tCL, tCH) refers to the smaller of the actual clock low time and the actual clock high time as provided to the device (i.e. this
value can be greater than the minimum specification limits for tCL and tCH).
10. tHP = minimum half clock period for any given cycle and is defined by clock high or clock low (tCH, tCL). tQHS consists of
tDQSQmax, the pulse width distortion of on-chip clock circuits, data pin to pin skew and output pattern effects and p-channel to
n-channel variation of the output drivers.
11. This derating table is used to increase tDS/tDH in case where the input slew-rate is below 0.5V/ns.

0.5V/ns and Slew Rate2=0.4V/n then the Delta Inverse Slew Rate=-0.5ns/V.

14. DQS, DM and DQ input slew rate is specified to prevent double clocking of data and preserve setup and hold times. Signal
transitions through the DC region must be monotonic.
15. tDAL = (tDPL / tCK ) + (tRP / tCK ). For each of the terms above, if not already an integer, round to the next highest integer.
tCK is equal to the actual system clock cycle time.
Example: For DDR400(D4) at CL=3 and tCK = 5.0 ns,
tDAL = (15 ns / 5.0 ns) + (18 ns / 5.0 ns) = (3.00) + (3.6)
Round up each non-integer to the next highest integer: = (3) + (4), tDAL = 7 clocks
16. For the parts which do not has internal RAS lockout circuit, Active to Read with Auto precharge delay should be
tRAS - (BL/2) x tCK.
17. tHZ and tLZ transitions occur in the same access time windows as valid data trasitions. These parameters are not referenced
to a specific voltage level but specify when the device output is no longer driving (HZ), or begins driving (LZ).
