Abstract: A non-volatile memory device includes a semiconductor substrate (16), a thin, 10-15 Angstroms thick, memory oxide layer (11), a silicon nitride layer (12), a 70-100 Angstroms thick interfacial oxide layer (13), and a polysilicon gate electrode (14). The interfacial oxide layer (13) is formed by chemical vapor deposition at a temperature in the range of about 600-625`C.

Abstract: A low voltage write non-volatile MNOSFET memory device preferably of n-channel type has a first relatively highly doped p+ channel region (27) and a second underlying less highly doped p- region (28). The device is written to a "1" state by applying a low voltage (+12V) to the gate (21) and simultaneously applying a suitable voltage to the source (12) and/or the drain (13) to induce avalanche breakdown in the channel.
