Optimized switching and retention characteristics of an MNOS memory device are obtained by using as a gate electrode material either metals or semi-metals having a high work function, in conjunction with a gate dielectric layer having a low density of trapping states throughout its volume. The preferred gate electrode materials are either titanium or p.sup.+ -doped polycrystalline silicon.
