摘要:
A non-volatile memory device includes a semiconductor substrate and a source and drain within the substrate. A dielectric stack is formed over the substrate. The dielectric stack includes a thin top dielectric layer. A gate electrode is formed over the dielectric stack. The memory device is operative to perform a direct tunneling channel erase operation in which a pair of charge storing cells within a charge storing layer are erased via direct tunneling through the thin top dielectric layer.
