Abstract
A memory cell array includes first wiring lines, and second wiring lines, the first and second wiring lines intersecting, and memory cells disposed in the intersections of the first and second wiring lines, the memory cells including a variable resistance element. A control circuit controls voltages of selected first and second wiring lines. The first wiring lines are arranged at a first pitch in a first direction perpendicular to a substrate and extend in a second direction parallel to the substrate. The second wiring lines are arranged at a second pitch in the second direction and extend in the first direction. The control circuit is configured to change voltages applied to a selected first wiring line according to the positions of the selected first wiring lines in the first direction.
