SEMICONDUCTOR INTEGRATED CIRCUIT

摘要

PROBLEM TO BE SOLVED: To reduce a through current of a Vcc/2 precharge type sense amplifier driving circuit. SOLUTION: Switching means QP and QN for controlling a subthreshold current flowing to a circuit (driving circuit) between the circuit and a positive power supply potential Vcc and between the circuit and a ground potential are provided in the circuit that operates mainly at an intermediate potential between the positive power supply potential and the ground potential.
