Abstract

By inserting copper (Cu) metal layer between platinum (Pt) and titanium dioxide (TiO 2), we have observed both unipolar and bipolar resistive switching characteristics in Pt/Cu/TiO 2/Pt stacked RRAM cell. In order to analyze the conduction mechanism, we have conducted I-V fitting. And based on measurement results of bias polarity dependency, we have found that copper plays a role as oxygen reservoir. It can explain redox mechanism in bipolar resistive switching cell.
