Abstract:
A semiconductor memory device according to an embodiment comprises a memory cell array configured from a plurality of row lines and column lines that intersect one another, and from a plurality of memory cells disposed at each of intersections of the row lines and column lines and each including a variable resistance element. Where a number of the row lines is assumed to be N, a number of the column lines is assumed to be M, and a ratio of a cell current flowing in the one of the memory cells when a voltage that is half of the select voltage is applied to the one of the memory cells to a cell current flowing in the one of the memory cells when the select voltage is applied to the one of the memory cells is assumed to be k, a relationship M2
