Heat has been the ceiling that has stopped us from building electronic devices that survive in harsh conditions. Not only do electronic devices begin to thermally throttle at high temperatures, but if they are pushed beyond 200 degrees, they stop working entirely.
But that might change, as a team at the University of Southern California may have broken through the thermal ceiling. In a study published in Science, researchers developed a new memory chip that kept working reliably at 700 degrees Celsius. For reference, that’s hotter than molten lava.

The device showed no signs of giving up. Seven hundred degrees was simply the limit of their testing equipment. “You may call it a revolution,” said Joshua Yang, the lead researcher on the project. “It is the best high-temperature memory ever demonstrated.”
How did they pull this off?
The chip is built like a tiny sandwich.
