1. DI b = data-in for column b; DO n = data-out for column n.
2. An interrupted burst of 4 is shown; one data element is written.

4. A10 is LOW with the WRITE command (auto precharge is disabled).
5. DQS is required at T1n, T2, and T2n (nominal case) to register DM.
6. If the burst of 8 is used, DM and DQS are required at T3–T3n because the READ command
