Write command to Precharge command interval (same bank):
When the precharge command is executed
for the same bank as the write command that preceded it, the minimum interval between the two commands is
1 clock. However, if the burst write operation is unfinished, the input data must be masked by means of
DQM, DQMU/DQML for assurance of the clock defined by t
DPL
.
