While DDR-II is not likely to become available in quantity until March this year from what we've been told, Lost Circuits have a very decent write up on the new memory technology which nobody should miss.
DDR (I) is approaching the end of its dominating role in the desktop space to be replaced by the second generation of double data rate memory starting at 400 MHz and using a conventional 64/72 bit parallel bus interface. Lower operating voltage, new features like on-die termination, off-chip driver calibration, Posted CAS and variable write latency sound intriguing but what is really lurking behind the new standard. We have seen claims of up to 72% power savings over DDR I and other miracle cures for any bandwidth issues faced by the PC industry. We have done the math ourselves found a few convenient errors in some of the manufacturer's descriptions of DDR II. Otherwise, DDR II looks very promising but who will benefit in the end?More information @ Lost Circuits
