HANOVER, GERMANY--While the PC industry is expecting the transition to DDR2 (double data rate 2) memory to get underway later this year, Advanced Micro Devices has no plans to modify its current chips to support DDR2 this year, the company said here today....................

AMD's integrated memory controller design is much more sensitive to latency, or delays in a signal's journey from one point on a chip to another, Crank said. The first DDR2 chips run at 400 MHz and 533 MHz, and that's not fast enough to overcome the increased latency associated with DDR2 memory, Crank said. Internal tests of AMD systems with 400-MHz and 533-MHz DDR2 chips actually ran slower than systems with 400-MHz DDR chips, he said.

By the time 667-MHz DDR2 chips roll around, AMD will be ready to embrace the new standard, Crank said. This should take place at some point in 2006.
