An NROM (nitride read only memory) cell, which is programmed by channel hot electron injection and erased by hot hole injection, includes a charge trapping structure formed of: a bottom oxide layer, a charge trapping layer; and a top oxide layer. The bottom oxide layer is no thicker than that which provides margin stability.
