developed a transistor inspired by human synapses – an innovation that is quite
possibly the closest we’ve come to imitating how the brain’s neurons connect.
This transistor boasts many similarities with human synapses: how it operates,
its ultra-low energy consumption and a similar level of miniaturization. It
opens the door to a future with more powerful circuits that will meet the needs
of artificial intelligence.
The transistor presented by CEA-Leti is analog. In other words, instead of having two possible states, open & closed, it has around 50 possible states. This enables it to reproduce how synapses function. Synapses act as the connection between brain neurons, which are activated when their synapses have recorded a certain number of electrical impulses. A transistor with several dozen states can imitate this behavior.
