Abstract

This semiconductor memory device comprises a memory cell array that includes: a plurality of first lines; a plurality of second lines intersecting the plurality of first lines; a plurality of memory cells each disposed at an intersection of the plurality of first lines and the plurality of second lines and including a variable resistance element; and a select transistor respectively connected to an end of the plurality of first lines. The select transistor includes a gate electrode, a gate insulating film, and a conductive layer. Moreover, one end of that conductive layer is connected to the end of the first line, and a non-linear resistance layer configured from a non-linear material is connected between the first line and the conductive layer.
