PURPOSE: A sense amplifier circuit is provided to increase a latch margin. CONSTITUTION: In the sense amplifier circuit for detecting a little potential differential generated by a memory cell and amplifying the little potential differential up to rail-to-rail in a flip flop(1) in the sense amplifier circuit, a next stage buffer(2) receiving a pair of complementary signals outputted from the flip flop(1) is configured by two logic circuits. The two logic circuits are configured with a NOR circuit or a NAND circuit. In each logic circuit, one adjacent to a carrier supply source among at least two serial-connected transistors is common to the two logic circuits.
