Abstract
Embodiments are directed to reduced power consumption for memory data transfer at high frequency through synchronized clock signaling. Delay locked loop (DLL) circuits are used to generate the synchronized clock signals. A DLL circuit consumes power as long as it is outputting the synchronized clock signals. A power saving apparatus and method are described wherein the DLL circuit is powered on when memory data access is active, while the DLL circuit is powered down when memory access is idle.
