  • Abstract
    Characteristics and their origin of a conductive filament in TaOx ReRAM are investigated. The results of systematic experimentation demonstrate that the formation of a small conductive filament with high density of oxygen vacancies, achieved by controlling the oxygen content of the resistance-switching material and forming/set current, is the key to achieving low-current switching combined with long retention.
