  • Abstract
    Stable bipolar RRAM devices were fabricated using bi-layer tantalum (Ta) oxide deposited by reactive magnetron sputtering at room temperature with asymmetric oxygen profiles. Impacts of oxygen profiles on the resistive switching characteristics were investigated through varying tantalum oxide thickness and oxygen partial pressure during tantalum oxide deposition. A preferred oxygen profile for tantalum oxide based RRAM is proposed to achieve better performance.
