Abstract
A nanoscale switching device has an active region containing a switching material capable of carrying a species of dopants and transporting the dopants under an electrical field. The switching device has first, second and third electrodes with nanoscale widths. The active region is disposed between the first and second electrodes. A resistance modifier layer, which has a non-linear voltage-dependent resistance, is disposed between the second and third electrodes.
