  • Publication number: 20090109727
    Abstract: The present method provides annealing of a resistive memory device so as to provide that the device in its erased state has a greatly increased resistance as compared to a prior art approach. The annealing also provides that the device may be erased by application of any of a plurality of electrical potentials within an increased range of electrical potentials as compared to the prior art.

  • Publication number: 20090067213
    Abstract: In fabricating a memory device, a first electrode is provided. An alloy is formed thereon, and the alloy is oxidized to provide an oxide layer. A second electrode is provided on the oxide layer. In a further method of fabricating a memory device, a first electrode is provided. Oxide is provided on the first electrode, and an implantation step in undertaken to implant material in the oxide to form a layer including oxide and implanted material having an oxygen deficiency and/or defects therein. A second electrode is then formed on the layer.

  • Publication number: 20080123401
    Abstract: A present method of fabricating a memory device includes the steps of providing a dielectric layer;, providing an opening in the dielectric layer, providing a first conductive body in the opening, providing a switching body in the opening, the first conductive body and switching body filling the opening, and providing a second conductive body over the switching body. In an alternate embodiment, a second dielectric layer is provided over the first-mentioned dielectric layer, and the switching body is provided in an opening in the second dielectric layer.

  • Publication number: 20060145134
    Abstract: A method for fabrication and a structure of a self-aligned (crosspoint) memory device comprises lines (wires) in a first direction and in a second direction. The wires in the first direction are formed using a hard mask material that is resistant to the pre-selected etch processes used for creation of the lines in both the first and the second direction. Consequently, the hard mask material for the lines in the first direction form part of the memory stack.

  • Publication number: 20050265072
    Abstract: A method and structure for a memory cell comprising a phase change material; a heating element in thermal contact with the phase change material, wherein the heating element is adapted to induce a phase change in the phase change material; and electrical lines configured to pass current through the heating element, wherein the phase change material and the heating element are arranged in a configuration other than being electrically connected in series. The memory cell further comprises a sensing element in thermal contact with the phase change material, wherein the sensing element is adapted to detect a change in at least one physical property of the phase change material, wherein the sensing element is adapted to detect a change in a thermal conductivity of the phase change material.

  • Patent number: 5703373
    Abstract: The present invention is a fiducial electron beam detector including an etron beam absorber layer having one or more apertures for transmitting an electron beam, and a conductive or semiconductive structure adapted to produce a current in response to an incident electron beam transmitted through an aperture. When electrons from the electron beam strike this structure, a flow of electrons is created which may be monitored using any of the known methods for detecting current flow.
