Title: Differential sense amplifier circuit

Abstract: Disclosed is an amplifier circuit comprising: an amplifier 1 which is activated when supplied with a control signal SE and which outputs a pair of amplified signals D and DC; a detection circuit 2 for detecting one of the pair of amplified signals D and DC being changed in potential and outputting a detection signal PO upon detection of the potential change; and a latching circuit 3 which receives a set signal S and the detection signal PO and which outputs the control signal SE. The latching circuit 3 starts outputting the control signal SE in response to an input of the set signal S and terminates the output of the control signal SE upon input of the detection signal PO.
