Notes: 1. An interrupted burst of 8 is shown; one data element is written.
2. A10 is LOW with the WRITE command (auto precharge is disabled).
3. PRE = PRECHARGE.
4. tWR is referenced from the first positive CK edge after the last data-in pair.
5. DQS is required at T4 and T4n to register DM.
6. If a burst of 4 is used, DQS and DM are not required at T3, T3n, T4, and T4n.
7. DINb = data-in for column b.
