Micron's DDR3 products will support data rates of 800 megatransfers per second (MT/s) to 1,600 MT/s with clock frequencies of 400 megahertz (MHz) to 800 MHz respectively, doubling the speed from DDR2. At DDR3's top speed, a 100,000-page document can be transferred in approximately one second. The DDR3 supply voltage has been reduced from 1.8V to 1.5V, reducing power consumption by up to 30 percent; the device is manufactured on Micron's 78nm process technology.
Currently there are not any commercial platforms available that support the DDR3 standard. However, chip developers are reprortedly already developing DDR3 platforms for debut next year.
"Early 2007 should bring memory thirsty computing and consumer applications, such as Microsoft's anticipated Vista operating system. DDR3 will initially benefit the server, notebook, and desktop markets and will then reach consumer applications such as graphics and HDTVs," said Shane Rau, senior analyst of IDC, a market intelligence firm.
Evaluation samples of Micron's 1Gb DDR3 components are available to select customers with production expected to begin early next year. Micron's 1Gb DDR3 components will be available in various output configurations (x4, x8 and x16), and will be fully compliant to the most recent JEDEC DDR3 specifications. These components will support module densities from 512 megabytes (MB) through 4 gigabytes (GB) and a variety of module types including FBDIMMs, UDIMMs, SODIMMs, and RDIMMs.
A 2Gb DDR3 device is also expected to be available from Micron early next year.
Korean-based Samsung has also unveilled 1Gb DDR3 prototypes while Elpida has already shipped sampled to Intel.
