Domain Wall Memory: The Next Big Thing in Hardware Security?
University of South Florida researchers recently set out to find a way to give consumers more bandwidth. What they stumbled upon, however, may very well become a valuable hardware network security tool. An article in IEEE Journal on Emerging and Selected Topics in Circuits and Systems details how the team originally investigated new ways to design cache using domain wall memory (DWM), which is ideal for the application due to its low standby power, fast access time and good endurance. The researchers tested a physics-based model of DWM to determine how it behaves under temperature, radiation and velocity. That’s when they inadvertently discovered that DWM’s characteristics make it a potential asset for hardware security purposes.

“Our original research sought to design new cache using DWM,” said Anirudh Srikant Iyengar, lead researcher of the group. “But once we determined how difficult hacking a system like this would be, we changed directions and started looking at hardware security. The way DWM is designed makes it extremely hard to copy. Hardware security could greatly benefit from this.”[…]
