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 or a bank-active
command.
3. Different bank:
When the bank changes, the write can be
performed after an interval of no less than 1
cycle, provided that the other bank is in the bank-
active state. However, DQM, DQMU/DQML
must be set High so that the output buffer
becomes High-Z before data input.
