Description

technical field [0001] The invention relates to the technical field of microelectronics, in particular to a memristor device based on an organic ferroelectric thin film material and a preparation method thereof. Background technique [0002] Memristor, also known as memristor, is a kind of non-linear circuit element with resistive memory effect, which can change the resistance state with the change of external electric quantity, thereby realizing the memory function. At present, memristor is the electronic device whose function is closest to that of neuron synapse, which can simulate the response behavior of organisms to external environmental stimuli. The special electrical properties of memristors provide the possibility for the realization of artificial neural networks and also promote the development of electronic skin. [0003] However, the memristive materials in existing memristors are usually inorganic metal oxides, sulfides, nanoparticle aggregates, etc., and the m...
