Aisin says its MRAM-based AI chip, built with Tohoku University, uses about 98% less power
The Toyota supplier told Nikkei Asia the magnetic-memory semiconductor consumes about 98% less power than similar existing chips; independent benchmarks and a production date were not given.
Why it matters
Moving data between memory and processors is one of the biggest energy costs in AI hardware, and magnetic RAM keeps data without constant power. Aisin, best known as an automotive parts maker, is pitching the chip for processing large amounts of data more efficiently, which matters for cars and edge devices where power is scarce. The 98% figure is the company's own comparison; watch for published measurements and any customer or production plans.
Key facts
- About 98% less power than similar existing chips (company)
