Power savings mode for memory systems

A system and method are disclosed to accomplish power savings in an electronic device, such as a memory chip, by performing selective frequency locking and subsequent instantaneous frequency switching in the DLL (delay locked loop) used for clock synchronization in the electronic device.

This DLL locking methodology allows for faster frequency changes from higher (during normal operation) to lower (during a power saving mode) clock frequencies without resorting to gradual frequency slewing to conserve power and maintain DLL locking. Hence, a large power reduction may be accomplished substantially instantaneously without adding complexity to the system clock generator.
