<p>A circuit for controlling operation/non-operation of a sense amplifier, which does not cause the operation speed of the sense amplifier to decrease yet maintaining correct and error-free operation, and which has a structure suited to higher integration. Sense amplifiers controlled by the control circuits are of a type comprising a pair of differential transistors and a transistor serving as a constant current source and connected to a common connection point of the differential transistors. A control means of the control circuit generates a constant current source control signal in response to a control signal representing instruction of operation/non-operation of the differential amplification of the paired transistors.</p> |
