Logic functions using interacting two-state m.o.s. devices

The turn-on and turn-off of a 2-state 2-terminal m.i.s. switching device is demonstrated by the introduction of an adjacent similar third electrode. Currents up to 30 times bigger have been switched off using the third terminal. The structure is then connected in a simple circuit to demonstrate first inverter action, and then the 2-input NOR gate function. The technology of the Structure is simple, the active region requiring no diffusions, and is m.o.s. compatible.
