Abstract
A middle electrode can be inserted at each intersection between a non-volatile memory element layer located on an electrically conductive word line and a non-linear element located on an electrically conductive bit line in a three-dimensional memory device. An oxygen-scavenging material portion can be provided between each electrically conductive word line and an adjoining insulator layer to scavenge oxygen from contacting portions of the non-volatile memory element layer, thereby forming an oxygen-scavenged non-volatile memory element portion that facilitates programming. The middle electrode and the oxygen-scavenged non-linear memory element portion can alter the programming characteristics of the non-volatile memory cells to provide easier and more reliable programming.
