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