Have you heard about the NIST synapse?
It sounded great until I read its works at temperatures close to absolute zero, and need to be cooled with liquid helium. That this might make the chips impractical for use in small devices, although a large data centre might be able o maintain them. … We don’t yet understand enough about the key properties of the [biological] synapse to know how to use them effectively.”
IST’s artificial synapse is a metallic cylinder 10 micrometers in diameter — about 10 times larger than a biological synapse. It simulates a real synapse by processing incoming electrical spikes (pulsed current from a neuron) and customizing spiking output signals. The more firing between cells (or processors), the stronger the connection. That process enables both biological and artificial synapses to maintain old circuits and create new ones.
Dramatically faster, lower-energy-required, compared to human synapses
But the NIST synapse has two unique features that the researchers say are superior to human synapses and to other artificial synapses:
