  • Patent number: 7154806
    Abstract: Disclosed herein is a differential amplifier control circuit in which a signal indicating that all banks are not activated is provided to a differential amplifier, so that the differential amplifier does not operate, thereby reducing unnecessary current consumption in an ICC2N situation. An all bank idle notification unit generates an all bank idle signal notifying that a plurality of banks are not activated using a plurality of bank active signals for activating the plurality of the banks. A differential amplifier controller generates a differential amplifier control signal for disabling a differential amplifier using an all bank idle signal and an internal clock signal. The differential amplifier does not operate in response to the differential amplifier control signal if the plurality of the banks is all inactivated.
