Note:
1. VDDQ must not exceed the level of VDD.
2. For DDR400, VDD=2.6V ± 0.1V, VDDQ=2.6V ± 0.1V
3. VIL (min) is acceptable -1.5V AC pulse width with < 5ns of duration.
4. 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.
5. VID is the magnitude of the difference between the input level on CK and the input level on /CK.
6. 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.
7. VIN=0 to VDD, All other pins are not tested under VIN =0V.
8. DQs are disabled, VOUT=0 to VDDQ.

Note:
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).

Output
(VOUT)
50 Ω
30 pF
Figure: Timing Reference Load
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.

184pin Registered DDR SDRAM DIMMs
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.

Note:
1. DM states are Don’t Care. Refer to below Write Mask Truth Table.
2. OP Code(Operand Code) consists of A0~A12 and BA0~BA1 used for Mode Registering 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+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+tWR+tRP). Write Recovery Time(tWR) is needed to guarantee that the last data has been
completely written.
5. If A10/AP is High when Row Precharge command being issued, BA0/BA1 are ignored and all banks are selected to be precharged.
