Santa Clara, Calif., Tokyo, Japan, Feb. 3, 2005 -Ovonyx, Inc. (`Ovonyx') and
Elpida Memory, Inc. ("Elpida") today announced that they have entered into an
agreement whereby Ovonyx has licensed Elpida to use its Ovonic Universal
Memory (OUM) thin-film semiconductor memory technology.  The technology
license agreement also provides that Ovonyx will actively support Elpida's
program to commercialization OUM phase change memory products.

Ovonyx memory technology uses a reversible phase-change memory process that has
been previously commercialized worldwide in rewritable CD and DVD optical memory
disks. The Ovonyx array-addressed semiconductor memory technology can be used in
applications such as DRAM replacements, as well as embedded applications in many
product areas such as microcontrollers and reconfigurable MOS logic.

"This agreement provides Elpida with exciting new options to advance memory
technology," said Yukio Sakamoto, president and CEO of Elpida Memory, Inc.
"Elpida plans to utilize Ovonyx' phase-change technology to further explore the
development of new DRAM features that will provide the high performance and low
current consumption required for next-generation mobile applications."

"Elpida is an industry leader in DRAM and a driving force in the development of
innovative memory technology," said Tyler Lowrey, President & CEO of Ovonyx.
"Phase change memory is a natural complement to DRAM, and we look forward to
working together."
