    Abstract: To provide enhanced data storage devices and systems, various systems, architectures, apparatuses, and methods, are provided herein. In a first example, a multi-layer resistive random access memory (ReRAM) array is provided. Active layers of the array each comprise a plurality of ReRAM elements that each include a gate portion having a gate terminal and a memory cell portion with a source terminal and drain terminal. Insulating layers of the array alternate with the active layers and each comprise an insulating material between adjacent active layers. Wordlines span through more than one layer of the array, with each of the wordlines comprising a column of memory cell portions coupled via source terminals and drain terminals of column-associated ReRAM elements. Bitlines each span through an associated active layer of the array, with each of the bitlines comprising a row of gate portions coupled via at least gate terminals of row-associated ReRAM elements.

    Abstract: An apparatus for high density memory with integrated logic. Specifically, a three terminal resistive random access memory (ReRAM) device having Schottky barriers that can switch from a low resistive state to a high resistive state is provided. The Schottky transistor memory device includes an insulating layer, a source region disposed on the insulating layer, a drain region disposed on the insulating layer, a binary or complex oxide memory material, a gate dielectric layer, and a gate electrode. As voltage is applied the Schottky barrier breaks down leading to the formation of a conductive anodic filament (CAF). The CAF is non-volatile and short-circuits the reverse-biased barrier thus keeping the device in a low resistance state. Removing the CAF switches the device back to a high resistance state. Thus, a new type of semiconductor device advantageously combines computation and memory further providing for very high density NAND chains.

    Abstract: Methods for improving the operation of a memory array by arranging a Metal-Insulator-Metal (MIM) structure between a word line and an adjustable resistance bit line structure are described. The MIM structure may correspond with a metal/ReRAM material/metal structure that is arranged between the word line and an intrinsic polysilicon region of the adjustable resistance bit line structure. In one example, a word line may be arranged adjacent to a ReRAM material that is adjacent to a first metal that is adjacent to the intrinsic polysilicon region. In another example, the word line may be arranged adjacent to a ReRAM material that is adjacent to a first metal that is adjacent to a second metal different from the first metal that is adjacent to the intrinsic polysilicon region.

    Abstract: Techniques are disclosed for forming non-planar resistive memory cells, such as non-planar resistive random-access memory (ReRAM or RRAM) cells. The techniques can be used to reduce forming voltage requirements and/or resistances involved (such as the resistance during the low-resistance state) relative to planar resistive memory cells for a given memory cell space. The non-planar resistive memory cell includes a first electrode, a second electrode, and a switching layer disposed between the first and second electrodes. The second electrode may be substantially between opposing portions of the switching layer, and the first electrode may be substantially adjacent to at least two sides of the switching layer, after the non-planar resistive memory cell is formed. In some cases, an oxygen exchange layer (OEL) may be disposed between the switching layer and one of the first and second electrodes to, for example, increase flexibility in incorporating materials in the cell.
