Discovery of a 'holy grail' with the invention of universal computer memory. A new type of computer memory to solve the digital technology energy crisis has been invented and patented by scientists. The device is the realization of the decades long search for a 'Universal Memory' to replace the $100 billion market for Dynamic Random Access Memory (DRAM) and flash drives. It promises to transform daily life with its ultra-low energy consumption, allowing computers which do not need to boot up and which could sleep between key strokes. Source 4d.
