1. VREF is expected to be equal to 0.5*VDDQ of the transmitting device, and to track variations in the dc level of same. Peak-to peak noise on VREF may
not exceed +/-2% of the dc value.
2. VTT is not applied directly to the device. VTT is a system supply for signal termination resistors, is expected to be set equal to VREF, and must track
variations in the DC level of VREF
.
3. VID is the magnitude of the difference between the input level on CK and the input level on CK.
4. 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.

14.0 Component Notes
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 speci-
fications and device operation are guaranteed for the full voltage range specified.
3. Figure 1 represents the timing reference load used in defining the relevant timing parameters of the part. It is not intended to be either a precise rep-
resentation 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).
VDDQ
50Ω
Output
(Vout)
30pF
Figure 1 : Timing Reference Load
4. AC timing and IDD tests may use a VIL to VIH swing of up to 1.5 V in the test environment, but input timing is still referenced to VREF (or to the cross-
ing 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. Enables on.chip refresh and address counters.
8. IDD specifications are tested after the device is properly initialized.
9. 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.
10. The output timing reference voltage level is VTT.
11. 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).
12. The maximum limit for this parameter is not a device limit. The device will operate with a greater value for this parameter, but sys tem performance
(bus turnaround) will degrade accordingly.
13. 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 previ ously 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.
14. A maximum of eight AUTO REFRESH commands can be posted to any given DDR SDRAM device.
15. For command/address input slew rate ≥ 1.0 V/ns
16. For command/address input slew rate ≥ 0.5 V/ns and < 1.0 V/ns
17. For CK & CK slew rate ≥ 1.0 V/ns
18. These parameters guarantee device timing, but they are not necessarily tested on each device. They may be guaranteed by device design or tester
correlation.
19. Slew Rate is measured between VOH(ac) and VOL(ac).
20. 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.
21. 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 dis-
tortion of on-chip clock circuits; and 2) The worst case push-out of DQS on one tansition followed by the worst case pull-in of DQ on the next transi-
tion, 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.
22. 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.
23. 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=7.5ns tDAL = (15
ns / 7.5 ns) + (20 ns/ 7.5ns) = (2) + (3) tDAL = 5 clocks

Example : For typical slew rate, DQ0 is switching
For minmum slew rate, all DQ bits are switching from either high to low, or low to high.
The remaining DQ bits remain the same as for previous state.
d. Evaluation conditions
Typical : 25 °C (T Ambient), VDDQ = 2.5V(for DDR266/333) and 2.6V(for DDR400), typical process
Minimum : 70 °C (T Ambient), VDDQ = 2.3V(for DDR266/333) and 2.5V(for DDR400), slow - slow process
Maximum : 0 °C (T Ambient), VDDQ = 2.7V(for DDR266/333) and 2.7V(for DDR400), fast - fast process
e. 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.
f. Verified under typical conditions for qualification purposes.
g. TSOPII package divices only.
h. Only intended for operation up to 266 Mbps per pin.
i. A derating factor will be used to increase tIS and tIH in the case where the input slew rate is below 0.5V/ns as shown in Table 2. The Input slew rate is
based on the lesser of the slew rates detemined by either VIH(AC) to VIL(AC) or VIH(DC) to VIL(DC), similarly for rising transitions.
j. 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 3 & 4. Input slew rate
is based on the larger of AC-AC delta rise, fall rate and DC-DC delta rise, 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 - 0.5ns/V . Using the table given, this
would result in the need for an increase in tDS and tDH of 100 ps.
k. Table 3 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 on the lesser of
the AC - AC slew rate and the DC- DC slew rate. The inut slew rate is based on the lesser of the slew rates deter mined by either VIH(ac) to VIL(ac) or
VIH(DC) to VIL(DC), and similarly for rising transitions.
l. DQS, DM, and DQ input slew rate is specified to prevent double clocking of data and preserve setup and hold times. Signal transi tions through the DC
region must be monotonic.

No operation (NOP) : Not defined
Note :
1. OP Code : Operand Code. A0 ~ A12 & BA0 ~ BA1 : Program keys. (@EMRS/MRS)
2. EMRS/ MRS can be issued only at all banks precharge state. A new command can be issued 2 clock cycles after EMRS or MRS.
3. Auto refresh functions are same as the CBR refresh of DRAM.
The automatical precharge without row precharge command is meant by "Auto".
Auto/self refresh can be issued only at all banks precharge state.
4. BA0 ~ BA1 : Bank select addresses.
If both BA0 and BA1 are "Low" at read, write, row active and precharge, bank A is selected.
If BA0 is "High" and BA1 is "Low" at read, write, row active and precharge, bank B is selected.
If BA0 is "Low" and BA1 is "High" at read, write, row active and precharge, bank C is selected.
If both BA0 and BA1 are "High" at read, write, row active and precharge, bank D is selected.
5. If A10/AP is "High" at row precharge, BA0 and BA1 are ignored and all banks are selected.
6. During burst write with auto precharge, new read/write command can not be issued.
Another bank read/write command can be issued after the end of burst.
New row active of the associated bank can be issued at tRP after the end of burst.
7. Burst stop command is valid at every burst length.
8. DM sampled at the rising and falling edges of the DQS and Data-in are masked at the both edges (Write DM latency is 0).
9. This combination is not defined for any function, which means "No Operation(NOP)" in DDR SDRAM.
