is minimum 1 CL K. A T ER M command to output disable latency is equivalent to the /CA S L atency.
As a result, RE AD to TE RM interval determines valid data length to be output. The figure below
shows examples of B L=8.
Burst read operation can be interrupted by a burst stop command(TE RM). RE AD to TE RM interval
CL=2 .0
CL=2 .5
