Patent ID: 7723820

Claim:
A semiconductor structure, comprising: a semiconductor substrate; an antifuse dielectric; a gate conductor located on and adjoining said antifuse dielectric; a first upper terminal adjoining said gate conductor; a second upper terminal adjoining said gate conductor and not adjoining said first upper terminal; a channel located directly underneath and adjoining said antifuse dielectric and located within said semiconductor substrate; and a source adjoining said channel and located within said semiconductor substrate; and a drain adjoining said channel and not adjoining said source and located within said semiconductor substrate, wherein said gate conductor, said antifuse dielectric, said channel, said source, said drain, and said semiconductor substrate form a MOSFET, wherein said first upper terminal is electrically connected to a second voltage supply or a third voltage supply through a selectable switching mechanism and said second upper terminal is connected to a fourth voltage supply through a switching device.
