Abstract
A resistive switching non-volatile memory element is disclosed comprising a resistive switching metal-oxide layer sandwiched between and in contact with a top electrode and a bottom electrode, the resistive switching metal oxide layer having a substantial isotropic non-stoichiometric metal-to-oxygen ratio. For example, the memory element may comprise a nickel oxide resistive switching layer sandwiched between and in contact with a nickel top electrode and a nickel bottom electrode whereby the ratio oxygen-to-nickel of the nickel oxide layer is between 0 and 0.85.
