[Read Interrupted by Write]
Burst read operation can be interrupted by write of the same or the
other bank. Random column access is allowed. In this case, the DQ
should be controlled adequately by using the DQMU / DQML to
prevent the bus contention. The output is disabled automatically 2
cycles after WRITE assertion.
