SEOUL -- Samsung Electronics Co. Ltd. here today claimed to be the first chip maker to develop a 128-megabit double data rate (DDR) SDRAM for graphics memory applications. The memory supports three-dimensional images and video storage using the DDR memory format, achieving data rates of 500 Mbits per second, according to Samsung.
The Korean memory maker said it expects the 128-Mbit DDR graphics memory to generate sales of $700 million in 2001. Samsung said the DDR memory chip is aimed at a range of 3-D graphics and video applications, including computer games, Internet systems, and high-end PCs.
The high-speed DDR format will help improve graphics performance in systems by two-and-a-half times over current chip designs, according to Samsung. Faster memories and higher levels of storage enable systems to produce more colors with higher resolution of images.
Samsung claims to have developed the DDR graphics memory with 0.17-micron design rules. The new chip supports image-refresh rates on displays that are three times better than the resolution of conventional televisions, the company said. Samsung said it has delivered samples of the new memory to leading suppliers of graphics chip sets.
