Abstract
Systems and methods for improving performance of a non-volatile memory that utilizes a Vacancy Modulated Conductive Oxide (VMCO) structure are described. The VMCO structure may include a layer of amorphous silicon (e.g., a Si barrier layer) and a layer titanium oxide (e.g., a TiO2 switching layer). In some cases, the VMCO structure or VMCO stack may use bulk switching or switching O-ion movements across an area of the VMCO structure, as opposed to switching locally in a constriction of vacancy formed filamentary path. A VMCO structure may be partially or fully embedded within a word line layer of a memory array.
