Write with auto-precharge:
In this operation, since precharge is automatically performed after completing
a burst write or single write operation, a precharge command need not be executed after each write operation.
The command executed for the same bank after the execution of this command must be the bank active
(ACTV) command. In addition, an interval of l
APW
is required between the final valid data input and input of
next command.
