An electronic synapse device comprising a substrate formed from semiconductor material; a first input for receiving a weighting signal; a second input for receiving a signal from a pre-synaptic neuron device; an insulating layer provided between the first and second inputs and the semiconductor material; and an output, the second input being located between the first input and the output. Upon application of the weighting signal to the first input, a quantity of charge accumulates in said substrate in the region of said first input. Subsequently, upon application of the pre-synaptic signal to the second input, the charge is transferred to a region of the substrate that is substantially in register with the second input whereupon the charge causes an output signal to be generated at the output.

L'invention concerne un dispositif de synapse électronique comprenant un substrat formé à partir d'un matériau semi-conducteur ; une première entrée destinée à recevoir un signal de pondération ; une seconde entrée destinée à recevoir un signal d'un dispositif de neurone présynaptique ; une couche isolante formée entre les première et seconde entrées et le matériau semi-conducteur ; et une sortie, la seconde entrée étant située entre la première entrée et la sortie. Lors de l'application du signal de pondération sur la première entrée, une quantité de charge s'accumule dans ledit substrat au niveau de la région de ladite première entrée. Ultérieurement, lors de l'application du signal présynaptique sur la seconde entrée, la charge est transférée vers une région du substrat qui coïncide sensiblement avec la seconde entrée, la charge entraînant la génération d'un signal de sortie au niveau de la sortie.
