Abstract
A device for implementing spike-timing-dependent plasticity is provided. The device includes a phase-change element, first and second electrodes disposed respective first and second surfaces of the phase-change element. The phase-change element includes a phase-change material with an inverse resistivity characteristic. The first electrode includes a first heater element, and a first electrical insulating layer which electrically insulates the first resistive heater element from the first electrode and the phase-change element. The second electrode includes a second resistive heater element, and a second electrical insulating layer which electrically insulates the second resistive heater element from the second electrode and the phase-change element.
