ABSTRACT:
A sense amplifier circuit has a sense amplifier disposed on a bit line of an AND array circuit; a switch for selecting an output of the sense amplifier; a power switch for the sense amplifier; and a device for turning the power switch on by using a turning-on signal with respect to the switch for selecting the output of the sense amplifier. When the output of the sense amplifier is selected by the switch, the power switch is turned on by using the turning-on signal of this switch so that the sense amplifier is operated. When a turning-off signal is transmitted from the switch of the sense amplifier and the output of the sense amplifier is not selected, the power switch is turned off by this turning-off signal.
