2. Same bank, different ROW address:  
3. Different bank:  
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.  
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.
