... 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. ...

... Simulations are significantly more accurate and realistic than a gross estimation of module capacitance when inductance and delay parameters associated with trace lengths are used in simulations. JEDEC modules are currently designed using simulations to close timing budgets. Component AC Timing and Operating Conditions Recommended AC operating conditions are given in the DDR2 component data sheets. Component specifications are available on Micron’ ...
