Abstract

A method of forming a non-volatile memory device may include forming a fin protruding from a substrate, forming a tunnel insulating layer on portions of the fin, and forming a floating gate on the tunnel insulting layer so that the tunnel insulating layer is between the floating gate and the fin. A dielectric layer may be formed on the floating gate so that the floating gate is between the dielectric layer and the fin, and a control gate electrode may be formed on the dielectric layer so that the dielectric layer is between the control gate and the fin. Related devices are also discussed.
