The second-generation 512-megabit XDR has a peak operating speed of 6.4GHz and is designed for high-performance broadband applications, including digital consumer electronics, network systems and graphic systems. The XDR DRAM is based on Rambus' XDR memory interface technology and offers an octal data rate, supporting transfers of eight data in a single clock cycle. The part number TC59YM916BKG transfers data at 4.8GHz with a 1.8V VDD and supports peak operation of 6.4GHz. It is thus four times faster than the 1.6GHz Graphic Double Data Rate (GDDR) memory chips and twelve times faster than best-in-class 533MHz PC memories. Samples of the chip are available now.
