Researchers at the Karlsruhe Institute of Technology, working in collaboration with researchers at universities in Oxford, Exeter and Munster, have developed the first ever permanent and non-volatile optical memory for computers.
This new optical memory system is designed to retain data for decades and decades without being powered. The device's unique construction and design allows it to store large numbers of bits in a multi-level memory environment that is contained in a single cell that is just a billionth of a meter in size. Memory can be held in a number of ways and doesn't have to be restricted to standard binary units, all within very short periods of time.
The advantages of this optical memory setup are numerous. This kind of technology could substantially enhance computer performance while at the same time bring down energy consumption, making for an all-round efficient and effective system.
