Abstract(in English) | In this study, we have investigated the resistive switching (RS) characteristics of Ni/Ta2O5/TiN stack structure devices. Two different RS characteristics were observed in the same device. After forming, it showed abrupt (digital) RS characteristics. On the other hand, the device that transitioned to a particular state by the application of voltage to the initial state showed gradual (analog) RS characteristics. Based on the electrical characteristics of the devices and the distribution of oxygen vacancies in the Ta2O5 layer, we propose an RS operation model. |
