CE Latency = 4, Burst Length = 1, 2, 4, 8, full page burst
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
DQMB for assurance of the clock defined by t
DPL
.
