5. Write Interrupted by Precharge & DQM
Note : 1. To inhibit invalid write, DQM should be issued.
6. Precharge
7. Auto Precharge
PRELIMINARY
* Note : 1. The row active command of the precharge bank can be issued after t
2. This precharge command and burst write command should be of the same bank, otherwise it is not precharge
interrupt but only another bank precharge of dual banks operation.
