Notes: 1. NOP commands are shown for ease of illustration; other commands may be valid at
these times.
2. BL = 4, AL = 1, and WL = 2 in the case shown.
3. Disable auto precharge.
4.
“Don’t Care” if A10 is HIGH at T11.
5. tWR starts at the end of the data burst regardless of the data mask condition.
6. Subsequent rising DQS signals must align to the clock within tDQSS.
7. DI n = data-in for column n; subsequent elements are applied in the programmed order.
8. tDSH is applicable during tDQSS (MIN) and is referenced from CK T6 or T7.
9. tDSS is applicable during tDQSS (MAX) and is referenced from CK T7 or T8.
