Read Interrupted by Precharge Command & Read Burst Stop Cycle (@Full page Only)
HIGH
Row Active
(A-Bank)
1. At full page mode, burst is wrap-around at the end of burst. So auto precharge is impossible.
2. About the valid DQ
s after burst stop, it is same as the case of RAS interrupt.
Both cases are illustrated above timing diagram. See the label 1, 2 on them.
But at burst write, Burst stop and RAS interrupt should be compared carefully.
Refer the timing diagram of "Full page write burst stop cycle".
