Abstract
A system and method for aligning clock signals in a DDR DRAM module is disclosed. The system includes a phase detector circuitry, a controllable delay circuit, a first delay circuit and a synchronizing circuit. A clock signal is simultaneously transmitted through the first delay circuit and the controllable delay circuit. Subsequently, the clock signals transmitted through the first delay circuit and the controllable delay circuit are captured at the output thereof, and fed as inputs to the phase detector circuitry. The phase detector circuitry determines whether the clock signals are in phase, and accordingly adjusts the delay associated with the controllable delay circuit until the two clock signals are determined to be in phase.
