BURST INTERRUPTION
[Read Interrupted by Read]
Burst read operation can be interrupted by the new Read command issued to any other bank.
Random column access is allowed. READ to READ interval is 1CLK as the minimum.

CLK
[Read Interrupted by precharge]
Burst read operation can be interrupted by precharge of the same bank. READ to PRE interval is 1 CLK
minimum. The time between PRE command to output disable is equal to the CAS Latency. As a result,
READ to PRE interval determines valid data length to be outputted. The figure below shows the examples of
BL=8.
