Rambus demos 4.3Gbps smartphone memory

Rambus today will demo a new RAM technology that it believes could be needed for more advanced visuals on smartphones. Labeled the Mobile Memory Initiative, the approach uses a variant of the separate, flexible clock speeds used in XDR memory (found in the PlayStation 3) but with very low-power, low variance signaling that creates very high bandwidth without ramping up the power draw. MMI would allow 4.3 gigabits per second from a single chip but a typical voltage of just 100mV, providing about five times the headroom of the 800-megabit mobile memory available today
