Note:
PRECHARGE command, a subsequent command to the same bank cannot be issued
until
the last data element(s).
In the case of a fixed-length burst being executed to completion, a PRECHARGE com-
mand issued at the optimum time (as described above) provides the same operation
that would result from the same fixed-length burst with auto precharge. The disadvan-
tage of the PRECHARGE command is that it requires that the command and address
buses be available at the appropriate time to issue the command; the advantage of the
PRECHARGE command is that it can be used to truncate fixed-length or full-page bursts.

The READ command may be to any bank, and the WRITE command may be to any bank. If
a burst of one is used, then DQM is not required.
The READ command may be to any bank, and the WRITE command may be to any bank.
