Edinburgh Researchers Predict Magnetic Memory Near Landauer Limit Energy

9/7/2026

20 4 Full Breakdown

Summary

Story summary

University of Edinburgh researchers created a framework to cut magnetic memory energy.
Simulations show the method could lower switching energy by orders of magnitude versus DRAM, STT-MRAM and SOT-MRAM.
Predicted energy needs approach the Landauer limit, the theoretical minimum for a single bit.
Dr. Elton Santos said the theory could apply to electrical currents and laser pulses and study offers design guidance.
