DDR2 provides faster speeds, better signal integrity, improved thermal characteristics and reduced power consumption - more than any other memory available today for the desktop, server, workstation and notebook markets.
The 1.8-volt JEDEC-compliant memory features high-speed data transfer rates of 667 Mbps or 533 Mbps, and will be offered in an 800 Mbps version by early next year. Pricing has dropped to where the cost of DDR2 is essentially on par with DDR1 on a per bit basis.
Samsung is now producing 256, 512 Mb and 1 Gb versions of DDR2 at 533 Mbps, plus 256 and 512 Mb versions of its new DDR2-667 memory. Samsung's DDR2-667 optimizes performance in both single-core and dual-core processor systems.
Features contained in DDR2 that are not available in other memory include on-die termination, 240-pin count, multiple drive controls, off-chip driver calibration and four-bit pre-fetch.
According to DE DIOS & ASSOCIATES research, DDR2 sales will increase from $1.5B in 2004 to $6.5B this year to $18B in 2006.
