Preliminary Data Sheet
11. Read/Write Command Interval
11.1 Read to Read Command Interval
During a read cycle, when new read command is issued, it will be effective after /CAS latency, even if the previous
read operation does not completed. READ will be interrupted by another READ.
The interval between commands is minimum 1 cycle. Each read command can be issued in every clock without any
restriction.
