Figure 29: WRITE to Precharge – Interrupting
NOTE:
1. DI b = data-in for column b.
2. Subsequent element of data-in is applied in the programmed order following DI b.
3. An interrupted burst of 8 is shown; two data elements are written.
4. tWR is referenced from the first positive CK edge after the last data-in pair.
5. A10 is LOW with the WRITE command (auto precharge is disabled).
6. DQS is required at T4 and T4n (nominal case) to register DM.
7. If the burst of 4 was used, DQS and DM would not be required at T3, T3n, T4 and T4n.
8. PRE = PRECHARGE command.
