SMIC ARM926EJ Processor Chip Successfully Validated

Shanghai, China -- May 25, 2005 -- Semiconductor Manufacturing International Corporation (SMIC; NYSE: SMI , HKSE: 981) announced today that its 0.13-micron chip using the ARM926EJTM microprocessor core and the associated Embedded Trace Macrocell TM (ETM9TM) on-chip debug peripheral have been successfully verified through ARMs stringent qualification process. This achievement reflects the growing collaboration between SMIC and ARM (LSE:ARM; Nasdaq:ARMHY), enabling SMIC to deliver more advanced and comprehensive chip manufacturing solutions to its customers.

The ARM926EJ core features a Jazelle technology-enhanced 32-bit RISC CPU with an instruction set that includes 16-bit fixed point DSP instructions to support ARM Thumb technology and Java bytecode execution. Working to enhance the performance of signal processing, the ARM926EJ core can be integrated in the circuit designs of chips used in communication and multimedia applications such as next-generation smart phones, PDAs, 3G baseband and application processors, digital still cameras, audio and video decoders, and automotive infotainment.

As a proven and long-standing IP partner of SMIC, ARM provides vital design support and tools that facilitate SMICs ability to offer advanced design and manufacturing solutions," said Paul Ouyang, Vice President of Design Services at SMIC. "The ARM926EJ processor delivers high-performance with low-power consumption. By using SMICs 0.13-micron process technology to qualify the ARM926EJ processor, SMIC is actively working to meet the demand for consumer applications in 0.13um technology. Looking ahead, we are eager to continue collaborating with ARM and to providing more design support to our customers worldwide."

Jun Tan, President of ARM China said, ARMs partnership with SMIC, one of the most advanced foundries in the world, will strengthen the design and manufacturing support for our customers. ARM is dedicated to supporting companies in China in product design and development through the ARM Connected Community, which provides value-added services and reduces time-to-market for our partners.

SMIC and ARM began working together on the ARM926EJ processor in 2004. The successful qualification of the ARM926EJ processor on SMICs 0.13 micron process will enable those fabless companies who have licensed the ARM926EJ Design Kit through the Foundry Program to tape out in SMIC with a silicon-proven Manufacturing Kit. SMIC has also qualified its 0.18-micron macrocells using ARMs ARM7, ARM922T, and ETM9 cores . SMIC and ARM will continue leveraging both companies strengths to help customers accelerate their time-to-market and enhance their competitive edge.
