A groundbreaking study conducted by researchers from the Agency for Space, Technology, and Research (A*STAR) and the National University of Singapore (NUS) has revealed an innovative microelectronic device that functions as a sustainable and high-performance “bit-switch”. This device leverages magnetic skyrmions to operate using 1,000 times less power than conventional memory technologies.
Currently, information and communication technologies (ICT) account for nearly 20 percent of global electricity usage. With the rise of artificial intelligence (AI) technologies necessitating vast amounts of data processing, there is a pressing need for more efficient computing solutions to reduce energy consumption.
Skyrmions, which are minuscule magnetic whirls that exhibit remarkable stability and efficiency, are at the heart of this research. Measuring a mere 10,000 times smaller than the width of a human hair, skyrmions offer the potential to revolutionize data processing for AI applications due to their compact nature and mobility.
The research team achieved electrical readout and switching of skyrmions’ states using a tunnel junction, a thin insulating barrier between two electrically conducting materials. This breakthrough allows for switching between states in skyrmions with 1,000 times less power than conventional commercial devices, enhancing performance without the need to scale down the device.
Dr. Anjan Soumyanarayanan, Principal Scientist at A*STAR’s Institute of Materials Research and Engineering (IMRE) and Assistant Professor at NUS Faculty of Science’s Department of Physics, stated, “They have unique attributes that can be exploited to implement various AI architectures with unprecedented efficiency and functionality.
Our microelectronic device provides the key to unlocking their vast potential for the future of computing.”
The team aims to refine the device’s performance and facilitate seamless integration into microprocessors using established approaches. Their research, which was recently published in the journal Nature, opens the door to a more energy-efficient and sustainable future for information and communication technologies.
