Description

technical field [0001] The invention belongs to the technical field of organic diode electric storage and memristor devices, and in particular relates to a flexible memristor with biological synapse simulation function and a preparation method thereof. Background technique [0002] With the rapid improvement of the integration and performance of microelectronic chips following Moore's Law, the traditional storage technology based on complementary metal oxide semiconductor (CMOS) technology is gradually approaching its physical limit, and the "storage wall" problem of computers is also becoming more and more serious. Become more and more serious, these hinder the further development of the computer. Therefore, new storage technologies and computing must be found to develop computers with larger storage capacity and faster processing speed. Based on the research of electronic science, Cai Shaotang put forward a hypothesis in circuit theory from the perspective of symmetry in ...
