DDR3 is likely to enable gigabit-rate data processing for DDR memories. While DDR-400 provided a bridge to DDR2-400 memory, it is expected that DDR2-800 will do the same for DDR3-800. Samsung said it will manufacture DDR3 memory initially in an 80 nm process with a likely commercial availability for notebooks, desktops and servers in early 2006.
Even although DDR3 will start to be produced late in 2005, don't expect it to appear in stores right away. It will take some time for the technology to trickle down the mainstream market; it is estimated that DDR3 will enter the market during 2007 and reach a market share of 65 percent by 2009.
