DESCRIPTION
The H5DU6462CTR is a 67,108,864-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 64Mb 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 internally 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
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).
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.
/CS
Input
Chip Select: Enables or disables all inputs except CK, /CK, CKE, DQS and DM. All commands are masked when Chip Select is registered high. Chip Select provides for external bank selection on systems with multiple banks. Chip Select is considered part of the
command code.
BA0, BA1
Input
Bank Address Inputs: BA0 and BA1 define to which bank an ACTIVE, Read, Write or
PRECHARGE command is being applied.
A0 ~ A11
Input
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).
/RAS, /CAS, /
WE
Input
Command Inputs: /RAS, /CAS and /WE (along with /CS) define the command being
entered.
DM
(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 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 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 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.

Note :
1. UDM, LDM states are Don’t Care. Refer to below Write Mask Truth Table.(note 6)
2. OP Code(Operand Code) consists of A0~A11 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
Prechagre command.
3. If a Read with Auto-precharge command is detected by memory component in CK(n), then there will be no command presented
to activate bank until CK(n+BL/2+tRP).
4. If a Write with Auto-precharge command is detected by memory component in CK(n), then there will be no command presented
to activate 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 have 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. Power must first be applied to VDD, then to VDDQ, and finally to VREF
(and to the system VTT). VTT must be applied after VDDQ to avoid device latch-up, which may cause permanent damage 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 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 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
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 Register 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 ready for normal operation.
1.
Apply power - VDD, VDDQ, VTT, VREF in the following power up sequencing and attempt to maintain CKE at LVCMOS 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.
• 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.

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 reset 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 command. 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

H5DU6462CTR Series
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 DDR266/333 and 3
clocks for DDR400 product.
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 returning 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 functions 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.

5. The ratio of the pullup current to the pulldown current is specified for the same temperature and voltage, over the entire temperature 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.
6. VIN=0 to VDD, All other pins are not tested under VIN =0V.
7. DQs are disabled, VOUT=0 to VDDQ

1. All voltages referenced to Vss.
2. Tests for ac timing, IDD, and electrical, ac and dc characteristics, may be conducted at nominal reference/supply voltage levels,
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 environment nor a depiction of the actual load presented by a production
tester. System designers will use IBIS or other simulation tools to correlate the timing reference load to a system environment.
Manufacturers will correlate to their production test conditions (generally a coaxial transmission line terminated at the tester electronics).

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 level (for timing referenced to CK, /CK) is the point at which CK and /CK cross; the input reference
level for signals other than CK, /CK is VREF.
8. The output timing reference voltage level is VTT.
9. Operation or timing that is not specified is illegal and after such an event, in order to guarantee proper operation, the DRAM must
be powered down and then restarted through the specified initialization sequence before normal operation can continue.
10. tHZ and tLZ transitions occur in the same access time windows as valid data transitions. 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).
11. The maximum limit for this parameter is not a device limit. The device will 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 monotonic and meeting the input slew rate specifications of the device. When no writes were previously in progress on the bus, DQS will be transitioning from High-Z to logic LOW. If a previous write was in progress, DQS could
be HIGH, LOW, or transitioning from 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 tested 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) 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).
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 crosstalk (tJIT(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 distortion of on-chip clock circuits; and 2) The worst case push--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 pin skew and 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 circumstances, tXSNR can be satisfied 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-written with valid data before a valid
READ can be executed.

3. Pullup slew rate is measured between (VDDQ/2 - 320 mV ± 250mV)
Pulldown slew rate is measured between (VDDQ/2 + 320mV ± 250mV)
Pullup and Pulldown slew rate conditions are to be met for any pattern of data, including all outputs switching and only 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 slew rate to pulldown slew rate is specified for the same temperature and voltage, over the entire temperature
and voltage range. For a given output, it represents the maximum difference 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), similarly 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 slew rate is based on the larger of AC-AC delta rise, fall rate and DC-DC delta rise, fall rate. 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), 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 rate and the DC-DC slew rate. 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), and similarly for rising transitions.
12. 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.
