[ Read Interrupted by Precharge ]
Burst read operation can be interrupted by precharge of
the same bank
. READ to PRE
interval is mini-mum 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=4.
