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.

[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.
