ABSTRACT:
A sense amplifier control circuit controls the activation and deactivation of sense amplifiers without a lowering of the operation speed of the sense amplifiers, correctly carries out a control operation without malfunctions, and is suitable for highly integrated circuits. The control circuit comprises a control unit, and each of the sense amplifiers comprises a pair of transistors forming a differential pair and a constant current source transistor connected to a common node of the differential pair. The control unit is connected to the constant current source transistors and generates a constant current source control signal in response to control signal indicating an activation or deactivation of the differential amplification operation of each differential pair.
