A memory or switching device includes a mesa and a first electrode conforming to said mesa. The device also includes a second electrode and a phase-change or switching material disposed between said first and second electrodes. The phase-change or switching material is in electrical communication with the first and second electrodes at a first contact region and a second contact region respectively. Also described is a method for making a memory or switching device. The method includes providing a first insulator and configuring the first insulator to provide a mesa. A first conductive layer is provided conforming to the mesa. A phase-change or switching material is provided over a portion of the first conductive layer, and a second conductive layer is provided over the phase-change or switching material. |
