➀ TDK has developed a spin-memristor for analog neural networks and built a network that can separate music, speech, and noise in real-time. The technology is based on a collaboration with CEA since 2020 and uses a 300mm-compatible spintronics semiconductor prototyping line at Tohoku University. ➁ The memristors are controllable, have low current leakage, and are robust against resistance drift, allowing for long-term data storage. ➂ TDK and CEA have implemented an analog algorithm that can separate the three types of sound, and the technology has a significantly lower power consumption compared to conventional digital neural network implementations.
