2. An interrupted burst of 4 is shown; two data elements are written.
3.
4. A10 is LOW with the WRITE command (auto precharge is disabled).
5. DQS is required at T2 and T2n (nominal case) to register DM.
6. If the burst of 8 was used, DM and DQS would be required at T3 and T3n because the READ
t
command would not mask these two data elements.
WTR is referenced from the first positive CK edge after the last data-in pair.
