Samsung Begins Mass Production of High-performance GDDR5 Memory Using 50-nm Class Process Technology

Samsung Electronics Co., Ltd., the world leader in advanced memory technology and the leading producer of high-end graphics memory, has begun mass producing GDDR5 graphics memory using 50-nanometer class process technology, the company said in a press-release.

"With our launch of GDDR5 chips in the beginning of 2009 we satisfy the increasing demand for higher performance graphics memory in PCs, graphic cards and game consoles," said Gerd Schauss, Director of Memory Marketing, Samsung Semiconductor Europe. "The advanced memory performance of the GDDR series will thus upgrade the gaming experience across all platforms."

Designed to support a maximum data transfer speed of 7.0Gbps (gigabits per second), Samsungs GDDR5 will render more life-like (3D) imaging with a maximum 28GB/s (gigabytes per second) bandwidth, which is more than twice that of the previous fastest graphics memory bandwidth of 12.8GB/s for GDDR4. The ultra-fast processing speed is equivalent to transferring nineteen 1.5GB DVD resolution movies in one second. The high image processing speed of the GDDR5 also supports the latest data formats (Blu-ray and full HD).

Unlike GDDR4, which processes data and images using the strobe-and-clock technique, the processing speed of the GDDR5 is much faster because it operates with a free-running clock that does not require the data read/write function to be synchronized to the operations of the clock.

By adopting 50nm class technology, Samsung expects production efficiency to rise 100 percent over 60nm class technology. In addition, Samsungs GDDR5 operates at 1.35 volts (V), which represents a 20 percent reduction in power consumption compared to the 1.8V at which GDDR4 devices operate.

Now available in a 32Megabit (Mb) x32 configuration and also configurable as a 64Mb x16 device, Samsung expects GDDR5 to account for over 20 percent of the total graphic memory market in 2009. The company also said it plans to expand the 50-nm process technology throughout its graphics memory line-up this year.
