The present invention relates to a resistive random access memory using the rare earth scandate thin film as the storage medium, comprising a substrate, an insulation layer, a first electrode layer, a resistive memory layer, and a second electrode layer. In the present invention, it uses an amorphous rare earth scandate layer as the resistive memory layer of the resistive random access memory. Therefore, the resistive random access memory using the rare earth scandate thin film as the storage medium having advantages of low operation voltage and low power consumption can easily be manufactured without using any forming process or thermal annealing process. Moreover, through the characteristics of unipolar resistance switching behavior revealed by the amorphous rare earth scandate layer, the resistive random access memory using rare earth scandate thin film as the storage medium is able to perform a high resistance state and a low resistance state.
