Abstract

A sense-amplifier circuit comprising a plurality of sub-sense-amplifiers corresponding to respective reference potentials can operate fast when used for a multivalued information memory. The sense amplifier circuit is composed of sub-sense-amplifiers having different polarities according to corresponding reference potentials: a sub-sense-amplifier SN3 having the highest reference potential is of N (polarity) type and a sub-sense-amplifier SP1 having the lowest reference potential is of P (polarity) type. All sub-sense-amplifiers can operate according to improved characteristics assuring a reduced access time.
