Abstract
A control circuit controls a voltage applied to a memory cell array. A first electrode contacts to a first surface of a variable resistance element, while a second electrode contacts to a second surface of the variable resistance element. The first electrode is configured by a metal, and the second electrode is configured by a P type semiconductor. The control unit, when performing a setting operation of a memory cell, applies a voltage such that a current flows in a direction from the first electrode toward the second electrode.
