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

... Design Considerations Simulations Micron memory modules are designed to optimize signal integrity through carefully designed terminations, controlled board impedances, routing topologies, trace length matching, and decoupling. However, good signal integrity starts at the system level. Micron encourages designers to simulate the signal characteristics of the system’s mem- ory bus to ensure adequate signal integrity of the entire memory system ...
