Big Ideas for Brain-Inspired NanocircuitsGarrett RoseEngineering
Can you imagine machines with the
computational power of the brain (some brains at least) implemented at a scale
smaller than the diameter of a human hair? While such extreme examples are
unlikely in the near future, a path is unfolding toward brain-inspired
computers built from electronic devices fabricated at nanometer scales.
Specifically, nanoelectronic memristors (or “memory resistors”) are considered
for new forms of low-power, high-density computing. In this talk, we will
discuss research aimed at implementing brain-inspired systems where the
memristors act as artificial synapses, a key functional element in any neural
network. Results thus far have been promising in that we can model and simulate
networks trained for application areas such as pattern recognition and even
basic control. While we aren't building brains, not yet at least, such
power-efficient brain-inspired systems are expected to enable a range of
applications not easily possible with conventional computers.
