Claim Text:
1. An electronic device comprising an electronic memory unit, the electronic memory unit comprising one or more two-terminal multi-state memory cells configured to store information, the two-terminal multi-state memory cells comprising: a pair of electrodes respectively configured to conduct a current at a first electrical resistance; an insulating switching medium positioned between the pair of electrodes and configured to conduct the current at a second electrical resistance that is different than the first electrical resistance; and a conductive filament configured to form and to rupture within at least a portion of the insulating switching medium in response to a bipolar mode of operation and in response to a unipolar mode of operation, wherein the conductive filament, when formed, causes the insulating switching medium to conduct the current at less than the second electrical resistance, and wherein the conductive filament, when ruptured, causes the insulating switching medium to conduct the current at substantially the second electrical resistance.
