... READs and by the memory controller during WRITEs. DQS is edge- aligned with data for READs and center-aligned with data for WRITEs. DDR2 SDRAM modules operate from a differential clock (CK and CK#); the crossing of CK going HIGH and CK# going LOW will be referred to as the positive edge of CK. ...
