... DRAM core and eight corresponding n-bit-wide, one-half-clock-cycle data trans- fers at the I/O pins. DDR2 modules use two sets of differential signals: DQS, DQS# to capture data and CK and CK# to capture commands, addresses, and control signals. Differential clocks and data strobes ensure exceptional noise immunity for these signals and provide precise crossing points to capture input signals ...

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