Cumulative probabilities of the set and reset voltages and the LRS and HRS currents. Cumulative probabilities of the set and reset voltages of the sample fabricated at RT under the (a) bipolar and (b) unipolar modes. The set and reset voltages under the bipolar mode are distinguishable. (c) Cumulative probabilities of the HRS currents measured at 0.1 V and the LRS currents measured at -0.1 V under the bipolar mode. Two memory states are distinguishable.
