“…2 Henceforth, this caused the wide attention in both academia and industry. A memristor is a passive two-terminal nonlinear component, 3 and it has huge potential in nonvolatile memory, 4,5 large-scale integrated circuit, 6 biological bionics, 7 artificial neural networks, 8 pattern recognition, 9,10 picture processing, 11–13 and chaotic circuits. 14 Because of its unique switch mechanism, natural memory function, continuous input and output characteristics, and nanoscale size, the memristive effect of HP memristor was achieved in a solid-state thin film two-terminal device by moving the doping front along the device.…”
