  • Patent number: 9287501
    Abstract: A resistive random access memory includes an oxygen-poor layer disposed on a first electrode layer and formed by indium tin oxide, indium oxide, tin dioxide, or zinc oxide. An insulating layer is disposed on the oxygen-poor layer and is formed by silicon dioxide or hafnium oxide. A second electrode layer is disposed on the insulating layer. A method for producing a resistive random access memory includes preparing a first electrode layer. An oxygen-poor layer is then formed on the first electrode layer. The oxygen-poor layer is formed by indium tin oxide, indium oxide, tin dioxide, or zinc oxide. Next, an insulating layer is formed on the oxygen-poor layer. The insulating layer formed by silicon dioxide or hafnium oxide. A second electrode layer is then formed on the insulating layer.

  • Patent number: 9281475
    Abstract: A resistive memory cell is disclosed. The resistive memory cell comprises a pair of electrodes and a multi-layer resistance-switching network disposed between the pair of electrodes. The multi-layer resistance-switching network comprises a pair of carbon doping layers and a group-IV element doping layer disposed between the pair of carbon doping layers. Each carbon doping layer comprises silicon oxide doped with carbon. The group-IV doping layer comprises silicon oxide doped with a group-IV element. A method of fabricating a resistive memory cell is also disclosed. The method comprises forming a first carbon doping layer on a first electrode using sputtering, forming a group-IV element doping layer on the first carbon doping layer using sputtering, forming a second carbon doping layer on the group-IV element doping layer using sputtering, and forming a second electrode on the second carbon doping layer using sputtering.

  • Publication number: 20150349251
    Abstract: A resistive memory cell is disclosed. The resistive memory cell comprises a pair of electrodes and a resistance-switching network disposed between the pair of electrodes. The resistance-switching network comprises a group-IV element doping layer and a porous low-k layer. The group-IV doping layer comprises silicon oxide doped with a group-IV element. The porous low-k layer comprises porous silicon oxide or porous hafnium oxide. The group-IV element may comprise zirconium, titanium, or hafnium. The porous low-k layer may be prepared by inductively coupled plasma (ICP) treatment. A method of fabricating a resistive memory is disclosed. The method comprises forming a resistance-switching network on a first electrode using sputtering and forming a second electrode on the resistance-switching network using sputtering. The resistance-switching network comprises a group-IV element doping layer and a porous low-k layer.
