1. DI b = data-in for column b.
2. An interrupted burst of 8 is shown; one data element is written.
3.
4. A10 is LOW with the WRITE command (auto precharge is disabled).
5. DQS is required at T4 and T4n (nominal case) to register DM.
6. If the burst of 4 is used, DQS and DM are not required at T3, T3n, T4, and T4n.
