Cumulative probability of formation voltage and leakage current. (a) Formation voltages and (b) leakage currents depend on the device sizes and thickness of the Al2O3 films for the Al/Cu/Al2O3/TiN CBRAM devices with sizes of 8 × 8 and 0.4 × 0.4 μm2. The thicknesses of Al2O3 film are 2, 5, and 10 nm.
