SYNAPTIC CHAIN COMPRISING SPINTRONIC RESONATORS BASED ON THE INVERSE SPIN HALL EFFECT AND NEURAL NETWORK COMPRISING SUCH A SYNAPTIC CHAIN

摘要

The invention relates to a synaptic chain (110) of a neural network, the synaptic chain (110) comprising: a converter (C5) made of a metal having a strong inverse spin Hall effect; a transmission line (162); and synapses (112), each synapse being a spintronic resonator (164), the spintronic resonators being in contact with the converter (C5) and receiving signals, preferably hyperfrequency signals, particularly from neurons of a preceding layer, via the transmission line (162), each resonator (164) being a magnetic pad, each resonator having a resonance frequency, and each resonator generating a spin current, the amplitude of which depends on the ratio between the resonance frequency of the resonator and a reference frequency, the converter converting each spin current into a load current.
