A non-volatile memory device includes a channel structure extended in a first direction that includes a plurality of inter-layer dielectric layers and a plurality of channel layers alternately stacked over a substrate such that each inter-layer dielectric layer is adjacent to a corresponding one of the plurality of channel layers. A word line extends in a second direction crossing the first direction over the channel structure, and a gate electrode protrudes from the word line in a downward direction to contact a sidewall of the channel structure. A memory gate insulation layer is interposed between the gate electrode and the channel structure, where sidewalls of the channel layers contacting the gate electrode are protruded toward the gate electrode, compared with sidewalls of the inter-layer dielectric layers. |
