Modern SSDs are an engineering wonder. They're extremely fast and very reliable, despite being housed next to massive heat-belching graphics cards in gaming PCs. But like all silicon-based chips, they have limits to how hot they can run before losing data or failing completely. However, two teams of researchers have developed a type of flash memory that's capable of retaining data at temperatures that make an afternoon on Venus look cold in comparison.
The details of the work were published in the Nature journal (via Interesting Engineering), though the University of Pennsylvania nicely summarised the findings for those without a background in doctorate-level material science. Two research teams in the School of Engineering & Applied Science, headed by Deep Jariwala and Roy Olsson, dedicated months of work to finding the perfect thickness of ferroelectric aluminum scandium nitride (AlScN), to use as a base material for a flash memory device.
