Abstract
A sense amplifier circuit is disclosed in which a ROM is grouped into a plurality of ROM arrays and outputs from sense amplifiers provided for each ROM array are supplied to a single output terminal. In the sense amplifier circuit, each sense amplifier has a P-MOS FET connected between the output of the ROM array and a ground terminal and connected at the gate to a preset terminal, P-MOS FETs connected between the output of the ROM array and a positive power source and whose gates are respectively connected to the output terminal and a preset terminal, and an N MOS FET connected between the output terminal and the ground terminal and at the gate to the output terminal of the ROM array. Further, a P MOS FET is connected between the output terminal and the power source terminal and at the gate to an inverted preset terminal.
