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.
