Electronic apparatus, systems, and methods can include a resistive memory cell having a structured as an operably variable resistance region between two electrodes and a metallic barrier disposed in a region between the dielectric and one of the two electrodes. The metallic barrier can have a structure and a material composition to provide oxygen diffusivity above a first threshold during program or erase operations of the resistive memory cell and oxygen diffusivity below a second threshold during a retention state of the resistive memory cell. Additional apparatus, systems, and methods are disclosed. |
