January 16, 2026, 3:08 PM EST. Researchers in the United States and Japan unveiled a digital method to bias p-bits without bulky analog DACs, aiming to slash power in AI chips. The team uses MTJs that naturally flip between 0 and 1, feeding a digital circuit that controls how long to combine random bits and how to weigh them. The result is probabilistic computing that preserves randomness while dramatically reducing chip area and energy use versus DAC-based biasing. The work, presented December 10, 2025 at the IEDM in San Francisco and conducted with TSMC, also highlights self-organizing behavior that can prevent synchronized biasing. Co-author Shunsuke Fukami said digital control is key to progress.
