Rambus, Elpida, Toshiba announce XDR DRAM memory
Rambus Inc., Toshiba and Elpida today announced XDR DRAM memory utilizing Rambus XDR interface (former Yellowstone). According to the companies, 3.2GHz XDR DRAM offers 8 times the performance of existing memory types. XDR DRAM is designed for graphics workstations, servers, mobile systems and comms.
Initially they will offer 3.2GHz products, planning to increase the clock speed to 6.4GHz and higher to provide up to 100Gb/s performance. XDR DRAM chips will see the light in several variants differing by capacity (256Mbit to 8Gbit) and performance.
Toshiba and Elpida are expected to start sampling XDR DRAM in 2004, with volume production scheduled to 2005.
Below is the 512Mbit XDR DRAM chip architecture:
