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 I/On pins during this operation, the
CAS latency = 2, 3, burst length = 4
