A memory cell formed by forming a trench in the surface of a substrate. First and second spaced apart regions are formed in the substrate with a channel region therebetween. The first region is formed under the trench. The channel region includes a first portion that extends along a sidewall of the trench and a second portion that extends along the surface of the substrate. A charge trapping layer in the trench is adjacent to and insulated from the first portion of the channel region for controlling the conduction of the channel region first portion. An electrically conductive gate in the trench is adjacent to and insulated from the charge trapping layer and from the first region and is capacitively coupled to the charge trapping layer. An electrically conductive control gate is disposed over and insulated from the second portion of the channel region for controlling its conduction.
