Abstract

A non-volatile memory device includes an upwardly protruding fin disposed on a substrate and a control gate electrode crossing the fin. A floating gate is interposed between the control gate electrode and the fin and includes a first storage gate and a second storage gate. The first storage gate is disposed on a sidewall of the fin, and the second storage gate is disposed on a top surface of the fin and is connected to the first storage gate. A first insulation layer is interposed between the first storage gate and the sidewall of the fin, and a second insulation layer is interposed between the second storage gate and the top surface of the fin. The second insulation layer is thinner than the first insulation layer. A blocking insulation pattern is interposed between the control gate electrode and the floating gate.
