Abstract
A non-volatile memory cell that includes a Schottky barrier diode, located over a sub-diffused line or region formed within the substrate, acting as the control element. Information is stored in the device by introducing electrons into a nitride-oxide interface located at the perimeter of the Schottky barrier junction. Thus, the injected electrons are subject to trapping in the nitride-oxide layer, causing depletion in the epi region adjoining the diode interface, thereby influencing the current carrying state of the device.
