Zusammenfassung:A non-volatile semiconductor memory device includes a plurality of series-coupled fixed resistance elements, a plurality of reference cell transistors, and reference word lines coupled to gates of the reference cell transistors, a first reference data line coupled to one end of a resistance path in which a plurality of fixed resistance elements are arranged, and a second reference data line coupled in common to one ends of the reference cell transistors. The other end of each of the reference cell transistors is coupled to one of coupling points of the fixed resistance elements or the other end of the resistance path.
