Ordinary computer memory chips are vulnerable to temperatures above 300°C


A computer memory device that can withstand temperatures of more than 500°C could be used in spacecraft sent to explore Venus or the sun.

Computers use a technology called non-volatile memory to store data even after their power supply has been switched off — without it, today’s computers would consume too much power to be practical. However, these devices can’t currently withstand temperatures above 300°C, which means in extreme environments like the surface of Venus, which …
