Self-aligned, embedded phase change RAM
Abstract:
An integrated circuit with an embedded memory comprises a substrate and a plurality of conductor layers arranged for interconnecting components of the integrated circuit. An intermediate layer in the plurality of conductor layers includes a first electrode having a top surface, a second electrode having a top surface, an insulating member between the first electrode and the second electrode. A bridge overlies the intermediate layer between the first and second electrodes across the insulating member, wherein the bridge comprises a programmable resistive memory material, such as a phase change material. A conductor in at least one layer in the plurality of conductor layers over said intermediate layer is connected to said bridge.
