摘要
The required time for voltage-pulse-induced resistive switching of 40-nm-thick TiO2 thin films integrated in a contact-type structure (Pt top and TiN bottom contact, contact area similar to 0.07 mu m(2)) was studied as a function of pulse voltage. For off -> on switching at least 2 V was necessary and the minimum switching times were similar to 20 ns at 2 V and similar to 10 ns at 3 V. For on -> off switching, a minimum switching time of 5 mu s was obtained at 2.5 V. The resistance of the on-state device was also dependent on the switching voltage and time.
