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.

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.
