Samsung has developed two high-capacity memory parts, one of which will lead to higher-capacity storage cards for a range of consumer electronics, and another which will help PCs better handle memory-intensive applications such as 3D graphics processing.
One of the memory chips, an 8G-bit NAND flash memory chip based on extremely thin circuit and cell technology, will enable the company to develop 16GB memory cards that can contain up to 16 hours of DVD-quality video, or up to 4,000 songs of about five minutes each encoded in MP3 audio files. The other chip is a 2GB DDR2 SDRAM that will help workstations and servers process video and 3D-graphics applications.
NAND flash memory is mainly used in storage cards and in mobile phones. DDR2 is a more advanced variant of the most commonly used memory in PCs.
The 8GB flash chips are built on a 60nm process technology and have storage cells 30 percent smaller than the 70nm 4GB memory cells Samsung developed last year. A lower nanometer number means the circuits and memory cells can be made smaller, faster and less expensively.
"This is a ground-breaking technology and the memory should be available in 2007," said Kim Hyung Nam, principal analyst at iSuppli. "For the consumer, capacity matters, and with this technology the price could be reduced dramatically," he said.
For the 2GB DDR2 SDRAM, Samsung said that industry expected these to be made on a 65nm or smaller process, but the company made several innovations with transistor technology that enabled the parts to be made on an 80nm process. The company expects to start mass production of the parts in the second half of 2005.
"In terms of technology, 2GB DDR2 SDRAM is not a near-term product," said Hyung Nam. "Right now 256MB is mainstream and that's a quarter of the size. We don't think 512MB will become the main memory chip for PCs until 2008."
