2. Data-in at the cycle of interrupted by precharge can not be written into the corresponding memory cell. It is defined by
3. Burst stop is valid at every burst length.
AC parameter of t
DQM at write interrupted by precharge command is needed to prevent invalid write.
Input data after Row precharge cycle will be masked internally.
