Every year, the amount of digital information in the world increases nonlinearly. This trend makes it necessary to search for new modern memory elements, which requires solving problems of materials science, in particular, the development of technology for deposition of thin dielectric films with fundamentally new properties due to electromigration of oxygen vacancies or metal atoms in them. The paper presents the results of development of deposition process and research of titanium dioxide films modified (doped) with copper for creation of memristor structures on their basis. Their volt-ampere characteristics and resistive switching effect are studied. It is found that the proposed method of titanium dioxide preparation leads to a significant improvement of the basic memristive characteristics in comparison with memristive devices based on titanium dioxide without copper modification. In particular, it is demonstrated that the use of these films in the structure of the memristive memory element allows increasing the ratio of the state with high electrical resistance to the state with low electrical resistance by more than 102 times.
