A sense-amplifying circuit 10 which comprises a pair of inverters (TP0, TN0, TP1 and TN1), wherein an output of each inverter is connected to an input of the other inverter, drains of sensing transistors TN2 and TN3 are respectively connected to each source of the pair of inverters in series, the gates of both sensing transistors TN2 and TN3 are connected to differential input signal lines 12 and 14, and the sources of both sensing transistors TN2 and TN3 are connected through a common node with a transistor TN4, which works not only as a constant current source but also as an operation switch for the sense-amplifying circuit.
