A non-volatile memory includes a channel layer to extend from a substrate in a vertical direction; a plurality of interlayer dielectric layers and a plurality of gate electrodes to be alternately stacked along the channel layer; and a memory layer to be interposed between the channel layer and each of the gate electrodes, wherein the memory layer comprises a tunnel dielectric layer to contact the channel layer, a first charge trap layer to contact the tunnel dielectric layer and formed of an insulating material, a charge storage layer to contact the first charge trap layer and formed of a semiconducting material or a conductive material, a second charge trap layer to contact the charge storage layer and formed of an insulating material, and a charge blocking layer to contact the second charge trap layer.
