  • Patent number: 7943922
    Abstract: A nitrogenated carbon electrode suitable for use in a chalcogenide device and method of making the same are described. The electrode comprises nitrogenated carbon and is in electrical communication with a chalcogenide material. The nitrogenated carbon material may be produced by combining nitrogen and vaporized carbon in a physical vapor deposition process.
    Type: Grant

  • Patent number: 7692272
    Abstract: A non-volatile memory element comprises a bottom electrode 12; a top electrode 15; and a recording layer 13 containing phase change material and a block layer 14 that can block phase change of the recording layer 13, provided between the bottom electrode 12 and the top electrode 15. The block layer 14 is constituted of material having an electrical resistance that is higher than that of material constituting the recording layer 13. The block layer 14 suppresses the radiation of heat towards the top electrode 15 and greatly limits the phase change region when a write current is applied. The result is a high heating efficiency. The top electrode 15 itself can be used to constitute a bit line, or a separate bit line can be provided.
