The surface of a non-volatile memory device, designed to work in hostile environments such as those found in aerospace and nuclear industries. These metal-oxide-metal structures encode a bit in their electrical resistance, with the ability to reversibly switch between predetermined states. The drift of oxygen vacancies driven by an electric field can produce sudden oxygen explosions, damaging the top metallic electrode and producing micro-scale landscapes.
