Interval Between Read and Write Commands
A read command can be interrupted and a new write
command executed while the read cycle is in progress,
i.e., before that cycle completes. Data corresponding
to the new write command can be input at the point
new write command is executed. To prevent collision
between input and output data at the DQn pins during
this operation, the
CAS latency = 2, 3, burstlength = 4
