We have combined resonant interband tunneling diodes RITDs with giant magnetoresistance GMR elements so that the GMR element controls the switching current and stable operating voltage points of the hybrid circuit. Parallel and series combinations demonstrate continuous or two-state tunability of the subsequent RITD-like current voltage characteristic via the magnetic field response of the GMR element. Monostable bistable transition logic element operation is demonstrated with a GMRRITD circuit in both the dc limit and clocked operation. The output of such hybrid circuits is nonvolatile, reprogrammable, and multivalued.
