SILICON IMAGE accelerates move into serial ATA storage market by acquiring CMD TECHNOLOGY

SUNNYVALE, Calif., June 7, 2001 — Silicon Image, Inc. (Nasdaq: SIMG), a price/performance leader in high-bandwidth semiconductor solutions for mass markets, today announced it has acquired CMD Technology, Inc. (Irvine, Calif.), an established provider of high-performance and high-availability storage solutions that serve as the building blocks for Storage Area Networks (SANs). With this acquisition, Silicon Image accelerates its move into the Serial ATA segment of the storage market, another mass market that stands to benefit from Silicon Image's proven, robust, high-speed I/O technology.

CMD is a worldwide leader in SCSI and Fibre Channel storage controller solutions for the UNIX, Open Systems and PC markets, as well as a leading supplier of IDE/Ultra ATA semiconductors for the PC and embedded markets. CMD also provides a wide range of complementary software and firmware products and services, including its industry-renowned Medley™ RAID software. Counting Cisco, Compaq, Dell, HP, IBM and Sun Microsystems among its valued customers, CMD brings an experienced sales force, as well as strategic partnerships with an elite group of VARs, system integrators and resellers worldwide.

Enterprises face a tremendous challenge in managing data capture and retrieval in today's 24/7 business environment. The volume of data traffic over networks has increased exponentially due to the prevalence of the Internet and the proliferation of e-business applications and bandwidth-intensive digital content. This data explosion has increased both the demand for storage capacity and the need for increasingly faster data access and six sigma levels of data availability. As a result, high-speed, serial I/Os capable of unleashing enormous bandwidth have become a critical requirement in networked storage environments. Addressing this need, Fibre Channel has become the backbone of SANs, while Serial ATA is expected to supplant Parallel ATA for the mobile, desktop and entry-level server markets.

The combination of Silicon Image's field-proven, high-bandwidth, scalable semiconductor I/O solutions and CMD's extensive storage systems hardware and software expertise positions the combined entity to be a significant solutions provider for the emerging Serial ATA market. Market research firm IDC believes Serial ATA will become a viable alternative to SCSI for low-end systems, while ATA drives-including those with both parallel and serial interconnects-are anticipated to reach nearly 20 percent penetration of server shipments by 2004. Silicon Image is targeting this multi-billion-dollar opportunity and is now poised to speed the industry's transition from Parallel to Serial ATA and offer breakthrough price/performance to enterprise customers seeking robust SAN solutions based on Serial ATA.

Silicon Image President and Chief Executive Officer David Lee stated, "Silicon Image is executing its strategy of fully leveraging and diversifying its core, high-speed, serial link technology for multiple mass markets where bandwidth price/performance is crucial. We have become an industry leader and innovator in the PC/display realm with our PanelLink® interface and have since demonstrated the applicability of our Multi-layer Serial Link (MSL™) technology to the storage market — where we have demonstrated Serial ATA and multi-rate SerDes prototypes. We are committed to accelerating DVI adoption and growing our presence in the display market through continued innovation and integration, while also positioning the company to become a leading supplier of high-speed components for the Serial ATA and Fibre Channel markets."

"The CMD acquisition cements our position in the storage arena," said Steve Tirado, chief operating officer of Silicon Image. "Silicon Image and CMD have highly synergistic core competencies and technical talent. As a supplier of fully integrated, application-specific chip and board-level solutions with proven core components, the combined company will be uniquely and strongly positioned to attack the storage bandwidth price/performance challenge. In addition, the CMD acquisition provides Silicon Image with established sales channels, as well as strong and long-standing customer relationships we can utilize to populate the market with Serial ATA and Fibre Channel solutions." Tirado added, "Essentially, the CMD acquisition moves Silicon Image up the supplier food chain, bringing us closer to the enterprise customer. This represents a tremendous opportunity to provide high value-add solutions from the chip to the system level."

Privately held before the acquisition, CMD will now operate as a business division of Silicon Image. CMD operations and employees will remain in place, working under the leadership of Michael Kelley, who has been appointed general manager of the new division. Kelley has more than 20 years of enterprise systems experience and has been instrumental in Silicon Image's storage market initiatives in his most recent role as vice president of business development.

The transaction will be accounted for as a purchase. Under the terms of the acquisition, Silicon Image will issue approximately 6.4 million shares of Common Stock, in exchange for all issued and outstanding shares of CMD Technology. Silicon Image will assume CMD's outstanding stock options and will reserve approximately 3.7 million shares of Common Stock for the exercise of such options.

Silicon Image will host a conference call to discuss the details of the transaction at 5:30 a.m. PST on Friday, June 8, 2001. The call will be broadcast over the Internet and can be accessed at www.streetfusion.com or on the investor relations site located on www.siimage.com.
