Rambus says that they will be showing off with their XDR DRAM on this month's Intel Developer Forum, they will present a 512 megabit DRAM module from Toshiba running at 3.2GHz.
The firm also said Samsung will show off its XDR DRAM for the first time at the show. The memory type uses the XDR interface and the firm will claim that it offers eight times the bandwidth of the fastest PC memory currently available.
According to Rambus, mainstream DRAMs have problems delivering 1GHz+ data rates needed for high capacity memory, and use single ended signalling and multiple DRAM loads per data pin. That, it claims, limit maximum data rates to less than 1GHz.
