Abstract

See full text

A memory cell including a memory element comprising an electrolytic insulator in contact with a conductive metal oxide (CMO) is disclosed. The CMO includes a crystalline structure and can comprise a pyrochlore oxide, a conductive binary oxide, a multiple B-site perovskite, and a Ruddlesden-Popper structure. The CMO includes mobile ions that can be transported to/from the electrolytic insulator in response to an electric field of appropriate magnitude and direction generated by a write voltage applied across the electrolytic insulator and CMO. The memory cell can include a non-ohmic device (NOD) that is electrically in series with the memory element. The memory cell can be positioned between a cross-point of conductive array lines in a two-terminal cross-point memory array in a single layer of memory or multiple vertically stacked layers of memory that are fabricated over a substrate that includes active circuitry for data operations on the array layer(s).
