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.
WRITE to WRITE Command Interval (different bank)
Read command to Write command interval:
1. Same bank, same ROW address:
When the write command is executed at the same ROW address of
the same bank as the preceding read command, the write command can be performed after an interval of no
less than 1 clock. However, DQMB must be set High so that the output buffer becomes High-Z before data
input.
