New memory chip can survive extreme heat for future Venus, deep drilling missions

Researchers at the University of Southern California developed a memristor that operates reliably up to 1,292°F (700°C).

The device is built from tungsten, hafnium oxide, and graphene and kept data for over 50 hours at 700°C.

It survived more than one billion switching cycles at that temperature while operating at 1.5 volts with nanosecond switching speeds.

The team published the results in Science and noted applications including Venus missions, geothermal drilling, and high‑temperature AI computing.
