Abstract
A floating gate storage device in which the channel is maintained at a first doping concentration to provide a low threshold voltage and preselected portions or regions along the sides of the channel are maintained at a second higher doping concentration to enhance programming of the device. These regions are formed as part of the 'front-end' processing of the substrate while forming channel stops, thus no additional processing is required.
