DI b = Data In for column b
A interrupted burst of 4 or 8 is shown, 2 data elements are written
1 subsequent element of Data In is applied in the programmed order following DI b
tWTR is referenced from the first postive CK edge after the last desired Data In pair
The PRECHARGE command masks the last two data elements in the burst
A8 is LOW with the WRITE command (AUTO PRECHARGE is disabled)
*1 = can be don't care for programmed burst length of 4
*2 = for programmed burst length of 4, DQS becomes don't care at this point
