Figure 36 - DATA INPUT (WRITE) TIMING
DI n = Data In for column n
Burst Length = 4 in the case shown
3 subsequent elements of Data In are applied in the programmed
order following DI n

1. tDQSQ max occurs when DQS is the earliest among DQS and DQ signals to transition.
2. tDQSQ min occurs when DQS is the latest among DQS and DQ signals to transition.
3. tDQSQ nom, shown for reference, occurs when DQS transitions in the center among DQ signal transitions.
