NON-VOLATILE SEMICONDUCTOR MEMORY CELL UTILIZING TRAPPED CHARGE GENERATED BY CHANNEL-INITIATED SECONDARY ELECTRON INJECTION

The present invention provides a semiconductor device that comprises a tub region located in a semiconductor substrate, wherein the tub region has a tub electrical contact connected thereto. The semiconductor device further comprises a trap charge insulator layer located on the first insulator layer and a control gate located over the trap charge insulator layer. The control gate has a gate contact connected thereto for providing a second bias voltage to the semiconductor device that, during programming, is opposite in polarity to that of the first bias voltage.
