Teaching an Electronic Pavlov’s Dog: Memristive Devices in Neuromorphic Circuits

A memristor device is a non-linear resistive device with inherent memory: when current flows in one direction through the device, resistance increases; when current flows in the opposite direction, resistance decreases. When the current is stopped, the device retains its last resistance value. A memristor could therefore behave like a synapse in the brain: it can adopt high or low resistance states and retains information even when the current is switched off...By applying appropriate and timed stimuli and observing the electrical behavior of the circuit, the team showed that their circuitry too could learn to associate two previously independent stimuli. more
