Abstract

The nonvolatile memory device includes a control circuit that controls a sense amplification circuit and a writing circuit. The control circuit changes a value of at least one of (a) a load current and (b) a forming pulse current or a forming pulse voltage, according to a total number of sneak current paths formed by memory cells each including a variable resistance element in a second resistance state having a low resistance value except a selected memory cell in a memory cell array.
