Resistive switching characteristics of CuxO films grown by plasma oxidation process at room temperature are investigated.Both bipolar and unipolar stable resistive switching behaviours are observed and confirmed by repeated current-voltage measurements.It is found that the RESET current is dependent on SET compliance current.The mechanism behind this new phenomenon can be understood in terms of conductive filaments formation/rupture with the contribution of Joule heating.
