Magnetic-Feedback-Type Neural Circuit Based on a Variable-Synapse Coupling Device Using an MI Microsensor Array

This paper investigates a magnetic-feedback-type neural circuit based on a variable-synapse coupling device using an MI microsensor array. The proposed variable-synapse device is a magnetic coupling system for multiplication and accumulation. Analogue magnetic memory will be utilized to store the values of synapse couplings. The pulse modulation characteristics of the magnetic-feedback-type neural circuit are demonstrated. A pulse neural network system could be devised, using the magnetic synapse in combination with a pulse density modulation circuit.
