A sense amplifier includes: NMOS transistors, drains thereof being coupled to output nodes, gates thereof being coupled to the output nodes, sources thereof being coupled in common to the ground potential node; PMOS transistors, drains thereof being coupled to the drains of the NMOS transistors, sources thereof being coupled to the input nodes; PMOS transistors, drains thereof being coupled to the input nodes, gates thereof being coupled to the output nodes, sources thereof being coupled to the power supply node via a current source device; and NMOS transistors disposed between the output nodes and the ground potential node to be turned on before sensing; and an equalizing transistor disposed between the output nodes.
