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. By locking the DLL at a slow clock frequency, the operational frequency may be substantially instantaneously switched to an integer-multiplied frequency of the initial locking frequency without losing the DLL lock point. 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. Because of the rules governing abstracts, this abstract should not be used in construing the claims.
