| Zusammenfassung: | According to one embodiment, a differential circuit receives, as differential inputs, a readout signal read out from a semiconductor storage element and a reference voltage. An equalizing circuit controls, taking into account a state of a past input signal output from the differential circuit, the potential of the present differential signal output from the differential circuit. A sense amplifier detects a state of the differential signal output from the equalizing circuit. A state holding circuit holds a past state of the differential signal detected by the sense amplifier and supplies the state to the equalizing circuit. |
