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.

Boise, Idaho — Micron Technology on Wednesday, Dec 12, announced production sampling of its new 1Gb DDR2 device fabricated on 68-nanometer DRAM process technology.

The new process, coupled with Micron’s 6F² technology, has enabled the world’s smallest production 1Gb DDR2 memory with a die size of just 56mm². Mass production of its new 68nm 1 Gb DDR2 products is expected to begin early next year, with DDR3 and other low-power DRAM products expected to follow in the second half of the year.

This new advanced memory technology will be targeted at server, mobile and other computing applications where the benefits of reduced die size, faster speeds and lower power consumption are most critical.

Upcoming DDR3 products developed on the new process will allow for speeds up to 1600 megabits per second (Mbps). The 68nm process also provides approximately 20 percent lower power consumption when compared to previous process generations.

Future DDR3 chips designed on the 68nm process will join Micron’s Aspen Memory family of energy-efficient products, which are specifically designed for applications where power reduction is desired such as data center servers and notebook computers. More at Micron.

SAN JOSE, Calif –BUSINESS WIRE– Dec 01, ‘07 — Samsung Electronics announced today that it has developed the world’s fastest memory, a GDDR5 (series five, graphics double-data-rate memory) chip that can transfer data at six gigabits per second, which is more than four times faster than that of memories in state-of-the-art game consoles today.

Samsung’s GDDR5, which will be introduced at a density of 512 Mbit (16Mb x 32) chips, is capable of transmitting moving images and associated data at 24 gigabytes per second.

“We’re pushing image enhancement to a limit never before realized, enabling the smoothest, clearest animation that gamers have yet to experience,” said Mueez Deen, Marketing Director, Graphics Memory, Samsung Semiconductor. “Samsung’s 512Mb GDDR5 will enable the kind of graphics hardware performance that will spur software developers to deliver a new level of eye-popping games.”

The new Samsung graphics memory operates at 1.5 volts, representing an approximate 20 percent improvement in power consumption over today’s most popular graphics chip – the GDDR3.

Samples of Samsung’s new GDDR5 chip have been delivered to major graphic processor companies last month and mass production is expected in the first half of 2007.

Samsung expects that GDDR5 memory chips will become the de facto standard in the top performing segment of the market by capturing more than 50 percent of the high-end PC graphics market by 2010.

Hynix Introduces Industry’s First 1Gb GDDR5 DRAM

Samsung Intros Its Highest-Speed DDR2 Main Memory and Fastest Graphics Memory

Seoul, November 15, 2007 - Hynix Semiconductor today introduced the industry’s first 1 Gigabit GDDR5 Graphics DRAM.

GDDR, Graphics Double Data Rate, is an ultra high speed Graphics DRAM that processes graphic data in electronic devices such as personal computer and game consoles. As high definition digital media players market continues to expand, demand for high-speed and high density GDDR products is rapidly increasing.

The industry’s first 1Gb GDDR5 from Hynix is also the fastest and highest density graphics memory available. It operates at 5Gbps bandwidth and processes up to 20 Gigabytes of data per second with a 32-bit I/O, ideal in applications with high definition video and cinematic and photo-realistic graphics content. A bandwidth of 20 Gigabytes per second offered by the Hynix 1Gb GDDR5 can process more than 20 hours of DVD quality video.

The fifth generation graphics memory GDDR5 improves data processing speed by more than two times than that of GDDR3, the current mainstream graphics DRAM device. With its improved speed and power characteristics, GDDR5 is projected to succeed GDDR3 and dominate the graphics DRAM market from the 2nd half of 2008.

Hynix plans to start mass production of GDDR5 in the first half of next year to meet the increasing demand for high performance graphics DRAM. More at Hynix.
