Temperature impact on switching characteristics of resistive memory devices with HfOx/TiOx/HfOx stack dielectric
The forming free switching behavior is observed in the HfOx/TiOx/HfOx stack. Temperature dependent characteristics have been studied in 298373K range. No significant dispersion in set and reset voltage is observed at high temperature. The conduction is due to the formation of a high density of localized O-vacancies.
