It will supplement them. Optical Dynamic RAM and magnetic memory working together to enhance system performance. The Optical Dynamic RAM mirrors the magnetic data and during system on-time provides data access with nearly 1000 times smaller latency time. Where can Optical Dynamic RAM fit in the computing system and what are rough potential parameters. With suitable development this capability can substantially enhance performance in future communication systems.
Development is needed.
Some brave people will have to put in some serious money to make it happen.
