Abstract
To improve reading accuracy of a sense amplifier circuit and a semiconductor memory device. A sense amplifier circuit includes an N type FET which is a sensing transistor connected between a power supply and a ground via a data line that extends to a memory cell, a resistance element that is connected between a gate of the sensing transistor and the power supply, and a capacitance element that is connected between the gate of the sensing transistor and the ground.
