Abstract

A method of creating a nitride, programmable read only memory (NROM) cell includes the step of decoupling injection of channel hot electrons into a charge trapping layer of the NROM cell from injection of non-channel electrons into the charge trapping layer. The step of decoupling can include the step of minimizing the injection of the non-channel electrons into the charge trapping layer. Alternatively, it includes the step of minimizing the generation of the non-channel electrons. The present invention includes cells which have minimal injection of non-channel electrons therein.
