Abstract
Methods and structures are provided for a dual-bit EEPROM semiconductor device. The dual-bit memory device comprises a semiconductor substrate, a tunnel oxide disposed on the semiconductor substrate and first and second spaced apart floating gates that are disposed on the tunnel oxide. An interlayer dielectric layer contacts the tunnel oxide layer at a position between the first and second spaced apart floating gates and electrically isolates the first and second spaced apart floating gates. A control gate contacts the interlayer dielectric layer between the first and second spaced apart floating gates.
