Abstract

See full text

Insulated phase change memory devices are provided that include a first electrode; a second electrode; a phase change material disposed in an electrical path between the first electrode and the second electrode; and a porous dielectric configured to concentrate heat produced by a reset current carried through the phase change material between the first electrode and the second electrode to mitigate an amount of heat that escapes from the phase change material. The porous dielectric may be an inherently porous dielectric material or a dielectric material in which porous structures are induced during fabrication. Methods of fabrication of such devices are also provided.
