A structure of a memory cell in a memory device is taking an interface between a silicon nitride layer and a oxide layer. The memory cell includes: a polysilicon layer on a substrate, a silicon nitride layer on the polysilicon layer, an oxide layer on the silicon nitride layer, and a conductor layer on the oxide layer. The order of forming the silicon nitride layer and the oxide layer can be reversed either for another alternative structure of the memory cell. |
