7.6.2 Basic Write Timing Parameters
Basic Write timing parameters for DQs are shown in figure below; they apply to all Write operations.
Input data appearing on the data bus, is written to the memory array subject to the DM input logic level appearing
coincident with the data. If a given DM signal is registered Low, the corresponding data will be written to the memory;
if the DM signal is registered High, the corresponding data inputs will be ignored, and a write will not be executed to
that byte / column location.

1) DI n=Data In for column n
2) 3 subsequent elements of Data In are applied in the programmed order following DI n.
3) tDQSS: each rising edge of DQS must fall within the +/-25% window of the corresponding positive
clock edge.
