Nonvolatile resistive memory devices are disclosed. In some embodiments,
the memory devices comprise multilayer structures including electrodes,
one or more resistive storage layers, and separation layers. The
separation layers insulate the resistive storage layers to prevent charge
leakage from the storage layers and allow for the use of thin resistive
storage layers. In some embodiments, the nonvolatile resistive memory
device includes a metallic multilayer comprising two metallic layers
about an interlayer. A dopant at an interface of the interlayer and
metallic layers can provide a switchable electric field within the
multilayer.
