... DRAM core and eight corresponding n-bit-wide, one-half-clock-cycle data trans- fers at the I/O pins. DDR3 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 ...
