Abstract
A non-volatile memory having a control gate (14) and a sidewall select gate (28) is illustrated. The sidewall select gate (28) is formed in conjunction with a semiconductor doped oxide (20) to form a non-volatile memory cell (7). The semiconductor element used to dope the oxide layer (20) will generally include silicon or germanium. The non-volatile memory cell (7) is programmed by storing electrons in the doped oxide (20), and is erased using band-to-band tunneling.
