Abstract
A nonvolatile memory device includes a resistance switching layer, a gate on the resistance switching layer, a gate oxide layer between the resistance switching layer and the gate, and a source and a drain, spaced apart from each other, on the resistance switching layer. A resistance value of the resistance switching layer is changed based on an illumination of light irradiated onto the resistance switching layer and is maintained as a changed resistance value.
