Nonvolatile Memory Device Comprising a Metal-to-Insulator Transition Material

摘要

A nonvolatile memory device is disclosed comprising a metal-to-insulator transition material thermally coupled to a Peltier element. During programming, a selected current is flowing through the Peltier element, the level thereof determining whether the temperature of the Peltier element and hence of the thermally coupled metal-to-insulator transition material decreases or increases. In response to this temperature change, the metal-to-insulator transition material will change from one electrical conduction phase to another. The memory device is read by applying current through the metal-to-insulator transition material, the current level being selected to maintain the phase of the metal-to-insulator transition material.
