Patent ID: 8437174

Claim:
A memcapacitor device, comprising: a pair of opposing conductive electrodes; a semiconductive material comprising mobile dopants within a dielectric and a mobile dopant barrier dielectric material received between the pair of opposing conductive electrodes, the semiconductive material and the barrier dielectric material being of different composition relative one another which is at least characterized by at least one different atomic element, one of the semiconductive material and the barrier dielectric material being closer to one of the pair of electrodes than is the other of the semiconductive material and the barrier dielectric material, the other of the semiconductive material and the barrier dielectric material being closer to the other of the pair of electrodes than is the one of the semiconductive material and the barrier dielectric material; and the memcapacitor device comprising only a single terminal connected to one of the conductive electrodes and only another single terminal connected to the other of the conductive electrodes.
