TiO2 has attracted significant attention as a prototypical material for memristors. In this paper, a Cu-doped TiO2-x nanoscale memristor with structure of Ti/TiO2-x:Cu/Cu is built, whose faithful mathematical model is established based on the memristive behaviors and its switching mechanism. Using this model, a chaotic system is constructed and its complex dynamics are investigated by numerical simulations. Furthermore, hardware experiments are also designed to verify the model in chaotic circuit. The chaotic attractors obtained by simulations and hardware experiments are consistent, demonstrating the reliable performance of the Ti/TiO2-x:Cu/Cu memristor and the correctness of its mathematical model. The processes of memristor from manufacture and mathematical modeling to its verification in a chaotic circuit are presented.
