Conductive bridging RAM (CBRAM): an emerging non-volatile memory technology scalable to sub 20nm

Abstract

We report on the electrical characterisation of nanoscale conductive bridging memory cells, composed of a thin solid state electrolyte layer sandwiched between an oxidizable anode and an inert cathode. Low power resistive switching operation, the large scalability potential including multi-level-capability (MLC) and the investigated reliability aspects, like retention at elevated temperature, operating temperature and endurance, make CBRAM a very promising non-volatile emerging memory technology
