The
Joint
Electron Device Engineering Council (Jedec) has published the specifications
of the forthcoming Double Data Rate 3 (DDR3) memory standard.
DDR3 memory promises improvements in performance and power consumption over
DDR2 and older standards.
The new technology operates at 1.5V and offers an increased operating
temperature range. DD2 operates at 2.5V and DD1 used 1.8V. DDR3 also doubles the
pre-fetch buffer from 4-bit to 8-bit.
The new memory modules will especially shine in applications that require the
transfer of large amounts of memory. The decreases in power consumption will
also help increase battery life in laptops.
In a joint statement with the Jedec, Intel touted the technology as an
improvement for low-power mobile devices as well as high-end systems used for
gaming, video encoding or 3D visualisation.
Jedec expects that DDR3 memory will feature modules ranging from 512Mb to
8Gb. The chips will operate at transfer rates ranging from 800 to 1,600 million
transfers per second.
