DI a-b = data in for bank a, column b.
An interrupted burst is shown, 4 data elements are written.
3 subsequent elements of data in are applied in the programmed order following DI a-b.

TR
is referenced from the first positive CK edge after the last desired data in pair.
The Read command masks the last 2 data elements in the burst.
A10 is Low with the
W
rite command (Auto Precharge is disabled).
The Read and
W
rite commands are not necessarily to the same bank.
1 = These bits are incorrectly written into the memory array if DM is low.
