Abstract
The use of an O--N--RTN (Oxide-Nitride-Rapid Thermal Nitrided Polysilicon) interpoly dielectric multilayer instead of a customary O--N--O (Oxide-Nitride-Oxide) multilayer in the floating gate structure of a progammable, read-only memory cell has beneficial effects on the performance of the cell and facilitates its scaling.
