*Note:
1. Burst can鈥檛 end in full page mode, so auto precharge can鈥檛 issue.
2.Data-in at the cycle of interrupted by precharge can not be written into the corresponding memory cell. It is defined by
AC parameter of t
RDL
.
DQM at write interrupted by precharge command is needed to prevent invalid write.
Input data after Row precharge cycle will be masked internally.
3.Burst stop is valid at every burst length.
