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 clock. In the case of burst writes, the second write command has priority.

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