Note :
1. Absolute Specifications (0°C ≤ T
2. Impedance measurement condition for output source DC current: V
3. Mismatch is absolute value between pull-up and pull-down, both are measured at same temperature and voltage.
4. Slew rate measured from V
5. The absolute value of the slew rate as measured from DC to DC is equal to or greater than the slew rate as measured from AC to AC. This is
6. This represents the step size when the OCD is near 18 ohms at nominal conditions across all process and represents only the DRAM uncertainty.
Output slew rate load :
7. DRAM output slew rate specification applies to 667Mb/sec/pin and 800Mb/sec/pin speed bins.
8. Timing skew due to DRAM output slew rate mismatch between DQS / DQS and associated DQ is included in tDQSQ and tQHS specification.
