Researchers from the University of Edinburgh have created a new type of artificial synapse that can process information at room temperature. This innovation could lead to more energy-efficient computers and help address the growing demand for computing power.
Artificial intelligence is changing how we generate, process, and store information. However, its rapid growth also requires an enormous amount of electricity and computing power.
To solve this problem, researchers from the University of Edinburgh have developed a new approach to brain-inspired computing using tiny magnetic structures called skyrmions. These tiny structures behave like stable information carriers and can be used to create artificial synapses that operate at room temperature.
The human brain is very efficient because it processes memory and information together through networks of neurons and synapses. Computers, on the other hand, transfer information between separate processing and memory units, which makes them less efficient. The new synapse developed by the researchers tries to overcome this limitation by mimicking how our brains work.
The study used a special material called Fe₃GaTe₂, which is made up of tiny magnetic moments that can be arranged in different patterns. By changing these patterns, the researchers created a collective transformation of the magnetic state from a skyrmion lattice into stripe-like domains. This produced a linear and highly reproducible change in the material's electrical signal, which can represent the strength or 'weight' of an artificial synapse.
The new synapse can be tuned to create multiple information states and enable operations that are essential for modern neural networks. The researchers estimate that this new technology could save energy by consuming approximately 0.66 picojoules per operation, which is comparable to leading emerging technologies.
