and Symetrix announce a broad co-operation agreement for the
commercialization of FeRAMs
Tokyo, Japan, February 19, 2003, and Colorado Springs, February 18, 2003 - Oki Electric Industry Co., Ltd. (TSE: 6703) of Tokyo, Japan and
Symetrix Corporation of Colorado Springs, Colorado, USA have
announced a Cooperation and Licensing Agreement for the joint
commercialization of advanced NDRO (Non-Destructive Read Out) FeRAMs
(Ferroelectric Random Access Memories) based on Symetrix’ new
Trinion Cell technology. Under
the agreement, Symetrix licenses its NDRO-FeRAM technology to Oki,
and they collaborate on the development of a 16-Mbit FeRAM.
It is also agreed that Oki will provide Symetrix with foundry
services from its 0.25-micron fabrication facility.
"The partnership with
Symetrix is an essential one, as NDRO-FeRAM is a product that
responds to the customer needs for lower-power consumption advanced
non-volatile memories," stated Katsuhiko Sano, President of
Silicon Solutions Company at Oki Electric.
"Through the provision of the foundry function by Oki,
we believe that both companies can contribute to expansion of the
market, as well."
"This is an important
development for FeRAMs and for Symetrix," said Dr. Carlos Paz
de Araujo, Chairman of Symetrix.
"We are excited to be working with a great company like
Oki as Symetrix begins offering commercial FeRAM products.
Our new Trinion cell is a major breakthrough for high density
FeRAMs in both speed and power, and Oki will provide us with
first-class manufacturing capacity."
Oki has previously licensed
FeRAM technology from Symetrix, and will begin shipping embedded
FeRAM devices this year based on the licensed technology.
Devices that use this technology provide lower power
consumption and faster write speeds than other non-volatile memories
such as flash.
Building on this prior
success, Symetrix and Oki have now agreed to increase the scope of
the license to include the Symetrix high-speed and high-density next
generation memory cell, "Trinion Cell."
This represents a breakthrough in FeRAMs as it provides large
memories like those of 16-Mbit devices with extremely fast cycle
times of less than 20 nanoseconds, while operating at a mere 1.8
volts for both read and write operations.
The Trinion Cell also
provides NDRO technology that enables the cell to be read an
infinite number of times, unlike destructive-read memories, which
can only be read a limited number of times.
This characteristic expands FeRAM’s applications, including
its use for programming memory.
In addition, the cell makes optimal use of the already
low-fatigue layered perovskite (Y-1) technology owned by Symetrix.
Oki’s expertise in
manufacturing and product reliability was a major determining factor
in Symetrix entering into this collaboration.
The two companies have conducted research and development for
the past three years, culminating in the licensing of Oki by
Symetrix. Now, under
the new expanded licensing and cooperation agreement, Oki will also
provide foundry services for Symetrix and other licensees of its
The companies expect to have engineering samples by the end
of the year, and both companies will be marketing this product for
use in mobile devices such as mobile phones, PDAs, and game
products will enter the market first, followed by stand-alone
memories. As a result,
the alliance of Oki and Symetrix, the first sub-100-nanosecond
high-density FeRAM devices will enter the world market.
