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
.
WRITE to PRECHARGE Command Interval (same bank):
Burst Length = 4 (To stop write operation)
Burst Length = 4 (To write all data)
Bank active command interval:
1. Same bank:
The interval between the two bank-active commands must be no less than t
RC
