[ 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
DQMB0-7 to prevent the bus contention. The output is disabled automatically 1 cycle after
WRITE assertion.
