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

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