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...
