    摘要: Conductive oxide random access memory (CORAM) cells and methods of fabricating CORAM cells are described. For example, a material layer stack for a memory element includes a first conductive electrode. An insulating layer is disposed on the first conductive oxide and has an opening with sidewalls therein that exposes a portion of the first conductive electrode. A conductive oxide layer is disposed in the opening, on the first conductive electrode and along the sidewalls of the opening. A second electrode is disposed in the opening, on the conductive oxide layer.

    摘要: The present disclosure relates to the fabrication of spin transfer torque memory elements for non-volatile microelectronic memory devices. The spin transfer torque memory element may include a magnetic tunneling junction connected with specifically sized and/or shaped fixed magnetic layer that can be positioned in a specific location adjacent a free magnetic layer. The shaped fixed magnetic layer may concentrate current in the free magnetic layer, which may result in a reduction in the critical current needed to switch a bit cell in the spin transfer torque memory element.
