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.

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. 3. 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 tran sitioning 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. 4. A maximum of eight AUTO REFRESH commands can be posted to any given DDR SDRAM device. 5. For command/address input slew rate ≥ 1.0 V/ns 6. For command/address input slew rate ≥ 0.5 V/ns and < 1.0 V/ns 7. For CK & CK slew rate ≥ 1.0 V/ns 8. These parameters guarantee device timing, but they are not necessarily tested on each device. They may be guaranteed by device design or tester correlation. 9. Slew Rate is measured between VOH(ac) and VOL(ac). 10. 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. 11. 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 tansition 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 pchannel to n-channel variation of the output drivers. 12. 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. 13. 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 Rev. 1.2 May, 2004 256MB, 512MB Unbuffered DIMM System Notes : a. Pullup slew rate is characteristized under the test conditions as shown in Figure 1. DDR SDRAM Test point Output 50Ω VSSQ Figure 1 : Pullup slew rate test load b. Pulldown slew rate is measured under the test conditions shown in Figure 2. VDDQ 50Ω Output Test point Figure 2 : Pulldown slew rate test load c. Pullup slew rate is measured between (VDDQ/2 - 320 mV +/- 250 mV) Pulldown slew rate is measured between (VDDQ/2 + 320 mV +/- 250 mV) 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 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, typical process Minimum : 70 °C (T Ambient), VDDQ = 2.3V, slow - slow process Maximum : 0 °C (T Ambient), VDDQ = 2.7V, 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. m. 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 monotony.
