A charge trapping memory device in which a field induced inversion layer
is used to replace the source and drain implants. The memory cell are
adapted to store two bits, one on the left side and one on the right side
of the charge trapping structure. A positive threshold voltage erase
state is induced using negative gate voltage Fowler Nordheim FN tunneling
which establishes a charge balance condition at a positive voltage. A low
current, source side, hot electron injection programming method is used.
