Abstract:
The present techniques generally relate to fabrication of layered correlated electron materials (CEMs) in which a first group of one or more layers may comprise a first concentrationof a dopant species, and wherein a second group of one or more layers may comprise a second concentration of a dopant species. In other embodiments, a CEM may comprise one or more regions of graded concentration of a dopant species.
Abstract:
A memory element can include a first electrode; at least one switching layer formed over the first electrode; a second electrode layer; and at least one conductive cap layer formed over the second electrode layer having substantially no grain boundaries extending through to the second electrode layer; wherein the at least one switching layer is programmable between different impedance states by application of electric fields via that first and second electrode. Methods of forming such memory elements are also disclosed.
Abstract:
Providing for solid state memory having a non-linear current-voltage (I-V) response is disclosed herein. By way of example, the subject disclosure provides a selector device. The selector device can be formed in series with a non-volatile memory device via a monolithic fabrication process. Further, the selector device can provide a substantially non-linear I-V response suitable to mitigate leakage current for the non-volatile memory device. In various disclosed embodiments, the series combination of the selector device and the non-volatile memory device can serve as one of a set of memory cells in a 1-transistor, many-resistor resistive memory cell array.
Abstract:
Disclosed herein is a memory device operating based on proton conduction between a source electrode and a drain electrode through a proton-conducting layer. As the memory device operates, protons from the source migrate through the proton- conducting layer and into the drain electrode. The memory device exhibits memory, in the form of changing net conductivity, based on the amount of protons conducted from source to drain. The memory device can be reset by regenerating the source electrode (e.g., through electrical or chemical action). The memory device can be incorporated into an integrated circuit as a memory element. Related methods of using the memory device are also disclosed.

Abstract:
Providing for fabrication, construction, and/or assembly of a resistive random access memory (RRAM) cell is described herein. The RRAM cell can exhibit a nonlinear current- voltage relationship. When arranged in a memory array architecture, these cells can significantly mitigate sneak path issues associated with conventional RRAM arrays.
