ABSTRACT:
A method and apparatus for setting a floating gate in a floating gate circuit using dual conduction of Fowler-Nordheim tunnel devices is disclosed. In one embodiment, the present invention comprises a floating gate circuit having a single floating gate. During a set mode, the charge level on the floating gate is modified until it is set to a predetermined charge level that is a function of an input set voltage. In another embodiment, the floating gate circuit comprises two floating gates. During a set mode the charge level on each of the floating gates is modified until the difference in charge level between the two floating gates is a predetermined function of an input set voltage that is capacitively coupled to one of the floating gates during the set mode.
