Abstract

A conductive-bridge random access memory device is disclosed comprising a second metal layer configured to provide second metal cations; a layer of insulator adjacent to the second metal layer; the layer of insulator comprising a layer of first insulator and a layer of second insulator; the layer of second insulator being adjacent to the second metal layer; a first metal layer adjacent to the layer of first insulator, the first metal layer being opposite to the second metal layer; wherein the density of the layer of second insulator is higher than the density of the layer of first insulator.
