Abstract
An enhanced, scalable EEPROM memory cell is provided with a structure having a plurality of half-height tunnel oxide depletion mode transistors. The structure further has individual wordlines controlling the write and read transistors, respectively. With such a structure, lower voltages are used to program/erase the memory cell. The memory cell is scalable to small dimensions through the use of transistors having half-height tunnel oxide regions.
