Abstract
A sense amplifier circuit for use in a semiconductor memory device has complemented logic states at opposite sides of the latch circuit in the sense amplifier circuit determinate all the time in operation. The sense amplifier circuit takes advantage of a current mirror circuit for ascending or descending a voltage level at the gate of a transistor by charge accumulation or charge dissipation, which turns on or off the transistor so as to control the logic states at opposite sides of the latch circuit in the sense amplifier circuit.
