1. DI
b
= data-in for column
b
.
2. Three subsequent elements of data-in the programmed order following DI
b.
3. A burst of 4 is shown.
4. t
CDLR
is referenced from the first positive CK edge after the last data-in pair.
5. The READ and WRITE commands are to the same device. However, the READ and WRITE commands may be
to different devices, in which case t
CDLR
is not required and the READ command could be applied earlier.
6. A8 is LOW with the WRITE command (auto precharge is disabled).
7. WRITE latency is set to 3
