Q6: What are the main technology improvements in DDR3? How does it work?

Desi: Virtually all mainstream standard memory technologies are just incremental improvements over their previous versions. DDR3 is no exception. It is very much like DDR2 except it has lower power, and higher performance. It is always reasonable to expect that the next generation of any standard memory will ultimately gain about two times in raw performance and usually a few enhancements to make the actual performance even better than that. Expect the same from DDR3 all the way up to DDR3-1600. Reduced power consumption has also been a major focus as well in the development of DDR3.

Q7: Can you already reveal any details about DDR3, such as bus width, operating voltage and number of pins per module? When do you expect DDR3 to be adopted by the mass market?

Desi: For the questions you ask, DDR3 looks very much like DDR2 in that it has x4, x8 and x16 organizations and supports almost the same functions. The supply voltage will be 1.5V, and the modules, including unbuffered DIMM, registered DIMM and FB-DIMM2, will be physically the same size and shape, but with a few more pins for functionality. Following historical models, you could reasonably expect the same three-year transition to a new technology that you have seen for the last several generations of standard memory. Process improvements, controllers and systems, all have to be developed in parallel with the devices themselves, and the specification is not yet finished.
