HITACHI AND RAMTRON COOPERATE IN FERROELECTRIC PROGRAM

 COLORADO SPRINGS, Colo., Nov. 19 ~PRNewswire~ -- Hitachi, Ltd. (NYSE: HIT) and Ramtron International Corporation, a majority-owned subsidiary of Ramtron Holdings, Ltd. (NASDAQ: MEMRY), announced that they have commenced a joint program to integrate Ramtron's ferroelectric technology with Hitachi's DRAM manufacturing process. The companies began the six-month program in October 1992.
 According to the agreement, Hitachi will fabricate base wafers and Ramtron will perform its proprietary ferroelectric processing on 64-kilobit (kb) nonvolatile ferroelectric random access memory (FRAM(R)) test devices. Completed wafers will be evaluated by both parties. If successful characterization and reliability results are achieved, both parties will proceed with the joint development of high-density FRAM products of 256Kb density and greater.
 "We are very interested in Ramtron's ferroelectric technology," said Dr. Tsugio Makimoto, general manager of Hitachi's semiconductor & IC division. "Although there are many technical challenges to overcome, we expect ferroelectric technology to be a candidate for the ultimate nonvolatile RAM in the future."
 "We are extremely pleased with this opportunity to work with one of the world's leading companies," states George J. Stathakis, Ramtron's chairman and CEO. He continued, "Hitachi's world-class semiconductor capabilities combined with Ramtron's leading ferroelectric technology development can position FRAM memory as a major player in the high- density semiconductor market."
 High-density FRAM products are expected to compete in the computer memory market which is anticipated by Dataquest, a company of the Dun & Bradstreet Corporation, to exceed $15 billion by 1995. Advanced FRAM products will improve existing nonvolatile memory applications as well as allow new applications to emerge that cannot be served by existing technologies, such as nonvolatile main memory in portable computers.
 Hitachi, Ltd., headquartered in Tokyo, Japan, is one of the world's largest electronic and electrical equipment manufacturers, with operations extending to computers, semiconductors, household appliances, power generating equipment and industrial machinery. Hitachi's 1991 sales totaled $58.4 billion.
 Ramtron International Corporation develops, manufactures and markets FRAM products based on ferroelectric materials with unique nonvolatile and high-dielectric constant storage characteristics. Ramtron's FRAM products are produced at the company's Class 10 six-inch wafer fabrication facility in Colorado Springs. The company also develops and markets complementary metal oxide semiconductor (CMOS) high-performance specialty DRAMs. Ramtron holds 34 U.S. and foreign patents covering its proprietary technologies and products with an additional 95 patents filed.
