The picturesque town of Ivrea, which straddles the blue-green Dora Baltea River in northern Italy, is famous for its underdog kings. In 1002, King Arduin became the ruler of the country, only to be dethroned by King Henry II, of Germany, two years later. Today, the Bar di Re Arduino, a pub on a cobblestoned street in town, honors his memory, and that's where an unlikely new king was born.

The bar is the watering hole of Massimo Banzi, the Italian cofounder of the electronics project that he named Arduino in honor of the place. Arduino is a low-cost microcontroller board that lets even a novice do really amazing things. You can connect an Arduino to all kinds of sensors, lights, motors, and other devices and use easy-to-learn software to program how your creation will behave. You can build an interactive display or a mobile robot and then share your design with the world by posting it on the Net.

Computing With Chemicals Makes Faster, Leaner AI

Battery-inspired artificial synapses are gaining ground

Array of devices on a chip

This analog electrochemical memory (ECRAM) array provides a prototype for artificial synapses in AI training.

IBM research

How far away could an artificial brain be? Perhaps a very long way off still, but a working analogue to the essential element of the brain’s networks, the synapse, appears closer at hand now.

That’s because a device that draws inspiration from batteries now appears surprisingly well suited to run artificial neural networks. Called electrochemical RAM (ECRAM), it is giving traditional transistor-based AI an unexpected run for its money—and is quickly moving toward the head of the pack in the race to develop the perfect artificial synapse. Researchers recently reported a string of advances at this week’s IEEE International Electron Device Meeting (IEDM 2022) and elsewhere, including ECRAM devices that use less energy, hold memory longer, and take up less space.
