Read / Write Command Interval
Read to Read Command Interval
During a read cycle when a new read command is asserted, it will be effective after the
CAS
latency, even if the previous
read operation has not completed. READ will be interrupted by another READ.
Each read command can be asserted in every clock without any restriction.
Write to Write Command Interval
During a write cycle, when a new Write command is asserted, the previous burst will terminate and the new burst will begin
with a new write command. WRITE will be interrupted by another WRITE.
Each write command can be asserted in every clock without any restriction.
