CUPERTINO, Calif.--(BUSINESS WIRE)--Nov. 17, 1998--Siemens Semiconductors announced it has produced its first Double Data Rate (DDR) 1Gbit SDRAM. The chip is manufactured in 0.18micron CMOS technology with a minimum feature size of 0.175micron and has the industry's smallest chip area of 390mm2.
The 1Gbit SDRAM will be available in organizations of x16 and x32 and offers DDR functionality. This advanced feature enables the chip to achieve a data rate of 400 Mbit per second per pin making it the world's fastest DDR SDRAM devices. The 1Gbit SDRAM was developed together with IBM at the company's Advanced Semiconductor Technology Center (ASTC) in East Fishkill, N.Y. Samples packaged in 16mm-wide TSOP 88 will be available in the second quarter 1999.
"We are proud to present a chip of such a complexity at such a small die size in a technology which means we can achieve volume manufacturing in the near future," said Dr. Andreas v. Zitzewitz, president of Siemens Semiconductors' memory products division. "We have chosen four-level metalization (1 tungsten and 3 aluminum metal layers) to increase the cell efficiency and reduce die size. With our leading edge DRAM technology, we are able to supply our customers with the solutions they need to define future system architectures in the memory-hungry systems of tomorrow."
Main applications for the 1Gbit SDRAM are high-end servers, workstations, networking devices and specifically portable computing devices. Many new applications will be developed using the device's enormous storage capacity of about 70,000 pages of text or 90 minutes audio recording in stereo quality per chip.
In its 32bit-wide configuration, the device allows system data rates of 1.6Gigabyte/sec. Operating voltage is 2.5V. The device is based on the successful trench cell concept used in previous DRAM generations of Siemens Semiconductors.
