ABSTRACT:
The present invention includes a circuit, system and method for selectively turning off internal clock drivers to reduce operating current. The present invention may be used to reduce power consumption by reducing operating current in a memory device. Operating current may be reduced by turning off internal clock drivers that deliver a clock signal during selected periods of time. According to an embodiment of clock control circuitry of the present invention, an internal clock is disabled if a no operation command is detected during periods of time when no read or write burst operation is taking place. Methods, memory devices and computer systems including the clock control circuitry and its functionality are also disclosed.
