Interval Between Write and Read Commands
A new read command can be executed while a write cycle
is in progress, i.e., before that cycle completes. Data
corresponding to the new read command is output after
the CAS latency has elapsed from the point the new read
command was executed. The I/On pins must be placed in
the HIGH impedance state at least one cycle before data
is output during this operation.
CAS latency = 3, burstlength = 4
CAS latency = 2, burstlength = 4
