Abstract: PURPOSE:To increase erase speed and improve storage characteristics by designing a memory cell so that the chemical composition in the vicinity of the interface between the memory cell of CONIS structure and a tunnel insulator is closer in stoichiometry to Si3N4 rather than to the composition around the central portion of a silicon nitride film.
