Abstract

A memory device includes a first metal layer and a first metal oxide layer coupled to the first metal layer. The memory device includes a second metal oxide layer coupled to the first metal oxide layer and a second metal layer coupled to the second metal oxide layer. The formation of the first metal oxide layer has a Gibbs free energy that is lower than the Gibbs free energy for the formation of the second metal oxide layer.
