*Note : 1. Burst can’t end in full page mode, so auto precharge can’t issue.
2. About the valid DQs after burst stop, it is same as the case of RAS interrupt.
Both cases are illustrated above timing diagram. See the lable 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’.
3. Burst stop is valid at every burst length.
