Abstract

A super-silicon-rich oxide (SSRO) non-volatile memory cell includes a gate conductive layer on a substrate, a source/drain in the substrate at respective sides of the gate conductive layer, a tunneling dielectric layer between the gate conductive layer and the substrate, a SSRO layer serving as a charge trapping layer between the gate conductive layer and the tunneling dielectric layer, and an upper-dielectric layer between the gate conductive layer and the SSRO layer.
