Command Intervals
In the case of burst writes, the second write
command has priority.
Write command to Write command interval:
1. Same bank, same ROW address:
When another write command is executed at the
same ROW address of the same bank as the
preceding write command, the second write can
be performed after an interval of no less than 1
cycle.

2. Same bank, different ROW address:
3. Different bank:
When the ROW address changes, consecutive
read commands cannot be executed; it is
necessary to separate the two write commands
with a Precharge command and a bank-active
command.
When the bank changes, the second write can be
performed after an interval of no less than 1
cycle, provided that the other bank is in the bank-
active state. In the case of burst write, the second
write command has priority.
