ARM Becomes a Promoter Member of the Serial Port Memory Technology Consortium

ARM joins leading mobile market companies in the development, promotion and
adoption of the SPMT memory interface specification
SUNNYVALE, Calif.--(Business Wire)--
SPMT, LLC, the entity responsible for licensing the Serial Port Memory
Technology (SPMT) specification and administering the SPMT Consortium, today
announced that ARM [(LSE: ARM); (Nasdaq: ARMH)] has joined the SPMT Consortium
as a promoter member. Together with fellow Consortium promoter members Hynix
Semiconductor, Inc. (other-otc: HXSCF), LG Electronics (KRX: 066570), Samsung
Electronics Co., Ltd. (other-otc: SSNLF) and Silicon Image, Inc. (NASDAQ: SIMG),
ARM plans to promote serial port memory technology for broad market adoption as
an industry standard. Founded in May 2009, the promoter members of the SPMT
Consortium form the governing body of the organization and are responsible for
developing the SPMT specification.

Serial Port Memory Technology is the first-of-its-kind technology for dynamic
random access memory (DRAM) capable of delivering the bandwidth flexibility and
scalability required by new generations of mobile devices, all at significantly
reduced pin count, low power consumption and lower cost. The technology will
initially target the mobile handset market, enabling a new generation of devices
capable of running highly data intensive, media-rich applications while at the
same time extending battery life.

"ARM is a strong supporter of SPMT as a solution for reducing energy consumption
and providing the bandwidth capabilities required by future high-performance
mobile phones and portable computing devices such as netbooks," said Peter
Hutton, VP technology and systems, ARM. "Joining the SPMT Consortium as a
promoter member gives us an opportunity to participate in the establishment of
an industry standard that will enable many of the features demanded by the next
generation of mobile devices."

"The Consortium and its members are extremely pleased to have ARM, a company
whose technology solutions are powering the majority of mobile devices today,
join our organization," said Jim Venable, president of SPMT, LLC. "ARM`s
contribution and commitment to the SPMT standard will be invaluable in the
success of this new memory technology."

Opportunities to participate in the advancement of the Serial Port Memory
Technology exist for contributors and adopters. The SPMT promoters welcome
companies and organizations to contact the Consortium about joining the group.
