A nonvolatile memory device includes a plurality of interlayer dielectric layers and conductive layers for gate electrodes alternately stacked over a substrate, a channel trench passing through the interlayer dielectric layers and the conductive layers and exposing the substrate, a charge blocking layer and a charge trap or charge storage layer formed on sidewalls of the trench, a coupling prevention layer formed at the surface of the charge trap or charge storage layer, and a tunnel insulation layer formed over the coupling prevention layer.
