Next-generation HDTVs to use 4.8Gbps XDR DRAM
LOS ALTOS, Calif — Dec 17, `07 –BUSINESS WIRE– Rambus today announced that Toshiba Corporation has licensed its XDR memory controller interface cell (XIO) and XDR memory controller (XMC) for next-generation high-definition television (HDTV) chipsets. The XIO and XMC will be implemented in Toshiba’s 65nm process. Operating at 4.8Gbps, the XDR memory architecture will allow Toshiba’s HDTV chipset to deliver state-of-the-art image processing performance in its customers’ HDTVs.
The XDR memory architecture uses patented Rambus innovations such as Octal Data Rate (ODR) technology, Differential Rambus Signaling Level (DRSL), and FlexPhase circuits to deliver the highest bandwidth available while using fewer DRAM devices than industry-standard memory solutions. Higher memory performance as delivered by the XDR architecture enables the advanced features of next-generation HDTVs such as 1080p+ resolution, 120Hz refresh rates, 12-bit color, multiple full HD Picture-in-Picture (PiP) data streams, and advanced image enhancement algorithms.More here.
Tech-On! is reporting on the launch of new XDR DRAM by Elpida Memory Inc of Japan. In their words:
“Elpida Memory Inc of Japan has introduced the industry’s fastest DRAM, the 512-Mbit, 4.8GHz XDR DRAM, based on Rambus’ XDR memory architecture. The chip, the latest addition to the XDR DRAM family, offers an industry-leading data transfer rate of 9.6Gbytes per second with a single device, making it most suitable for high-performance, high-volume applications such as high-definition TVs (HDTV), gaming consoles, PCs, servers and workstations.
Elpida’s 512Mb, 4.8GHz XDR DRAM (EDX5116ADSE-5E-E) device is organized in 8-banks (x16/x8/x4 programmable), and with a 9.6Gbps data transfer rate delivers six times the peak bandwidth of industry-standard DDR2-800 memory devices. The 4.8GHz XDR device is manufactured using the company’s 70nm process technology and is available in a 104-ball FBGA package.”

“THINK THAT INTEL’S X48 chipset will be fast, with 2GHz DDR3 memory to accompany it? Think again - Intel’s old pal Rambus has them beaten like a grouse in hunting season.Elpida has just announced that it has the industry’s fastest DRAM, with its new XDR part running at a meltingly fast 4.8GHz. XDR is the Rambus standard for next-gen platforms, and its memory is included in the PS3, along with that console’s bonkers Cell processor.The Elpida RAM comes in 512MB chips, and runs at a 9.6GB/s transfer rate, which is about six times standard DDR2-800. You can also forget your average double data rate - this stuff runs with an octal data rate of 600MHz to get to 4.8GHz. Crazy.
