Abstract

Provision of fabrication, construction, and/or assembly of a two-terminal memory device is described herein. The two-terminal memory device can include an active region with a silicon bearing layer, an interface layer, and an active metal layer. The interface layer can created comprising a non-stoichiometric sub-oxide that can be a combination of multiple silicon and/or silicon oxide layers with an aggregate chemical formula of SiOX, where X can be a non-integer greater than zero and less than 2. The sub-oxide can be created in a variety of ways, including various techniques related to growing the sub-oxide, depositing the sub-oxide, or transforming an extant film into the sub-oxide.
