MIT engineers developed a chip the size of a piece of confetti, which consists of tens of thousands of artificial brain synapses. The latter are also known as poppy memristors, they imitate the process of transmitting information to the human brain, only it all happens on a small piece of metal. Information about the new development was published in the scientific journal Nature Nanotechnology.
Researchers have made a new device from alloys of silver, copper and silicon. It can “remember” images and play them repeatedly. Compared to previous versions of memristors, pictures are sharper and clearer. The developed chip is based on a new type of information processing: it imitates the neural architecture of the brain. Such a device can be integrated into small portable circuits to carry out complex computing tasks. Similar procedures can only be performed by modern supercomputers.
Now artificial synapse networks exist only in the form of software. Our team is trying to create equipment for neural networks in the form of portable artificial intelligence systems. Imagine that you connected this device to the camera of your car: it can recognize light sources, objects and instantly decide on further action. And all this without an internet connection. We hope to use energy-saving memristors to perform similar tasks in real time.

A transistor from a conventional circuit transmits information in the form of two values: 0 and 1, in turn, the memristor has a whole gradient of values, like a synapse in the brain. Such a feature would allow a single memristor to perform a wider range of operations than binary transistors. Scientists suggest that much fewer chips will be required than conventional transistors, this will create powerful portable computing devices that will not depend on supercomputers or on the Internet connection.
The new chip, which was developed by scientists from MIT, consists of tens of thousands of artificial synapses, or memristors. Each memristor that corresponds to a specific pixel in the image is stimulated by voltage, after which a new chip reproduces a given image. In our case, this is the shield of Captain America.
