Resistive switching random access memories are being thoroughly studied as prospective non-volatile memories. In this paper, we report electrical characterization of HfO2:Al2O3based metal-insulator–metal structures devised using atomic layer deposition. Dependences of electrical behavior on HfO2:Al2O3 cycle ratio is studied. An explanation for the differences between the Resistive Switching properties of the samples is proposed, based on the distribution of HfAlOx layers of the sample. Dependence of the RS properties of the samples on their growth temperature is discussed.
