New Scientist has a nice round up of some recent developments in computer memory, via Gnat’s four short links. I’ve talked about all but the RRAM before either here or on the podcast. The article is pretty dense but still accessible, quickly explaining the key aspects of each of the five techniques. There is also a nice summary on how each stacks up in terms of a few key metrics, including size, speed and power consumption. For each, the article only vaguely speaks to how far along each bit of research is, no real predictions or projections on when we might see each in our consumer electronics and/or personal computers.
