Memristive Devices for Neuromorphic Applications: Comparative Analysis

Neuromorphic systems must have at least five unavoidable features that are present in living beings. First, neuromorphic systems must perform memorizing and processing functions, using same elements. Second, it must allow data acquisition from sensors with preliminary processing and recording. Third, it must allow non-equilibrium processes, such as oscillator behavior at fixed values of input stimuli. Fourth, it must mimic some features of nervous systems. Fifth, it must permit possibility of coupling with living beings. In this paper, these features are considered with a special attention to how memristive devices can be implemented for reaching the goal. Comparison of characteristic properties of organic and inorganic memristive devices is discussed.
