Abstract
A resistive switching device includes a first electrode and a transition metal oxide layer formed on the first electrode. An oxygen scavenging electrode is formed on the transition metal oxide wherein the oxygen scavenging electrode removes oxygen from the transition metal oxide layer to increase formation of oxygen vacancies in the transition metal oxide layer to enable a switching mode when a bias is applied between the first electrode and the oxygen scavenging electrode.
