Synapse nano - electrical and method of training of such a synaptic

摘要

The invention relates to an electric synapse that comprises a main conductor with a predetermined potential V1, a secondary conductor said secondary conductor having a potential VX1+ that can vary between Vref−Vn and Vref+Vn, Vref being the reference potential, a nanoconductor with an adjustable conductance W1, the main conductor being connected to said secondary conductor through an adjustable conductance nanoconductor, one end at least of the main conductor being connected to an electric neuron, said electric neuron being capable of realizing a threshold function and applying a training control potential Va of Vref−Vp or Vref+Vp to the main conductor when the voltage O1 obtained at the output of said threshold function is different from the expected voltage T1, wherein the Vn and Vp potentials comply with: 2*VnVt and |Vp−Vn|Vt|Vp+Vn|.
