MoSys and Sarance Partner to Deliver Complete 40 Gigabit and 100 Gigabit Ethernet and Interlaken Solutions

SUNNYVALE, Calif., Jun 03, 2010 --MoSys, Inc. (NASDAQ: MOSY), a leading provider of differentiated, high-density memory and high-speed interface (I/O) intellectual property (IP), and Sarance, a leading supplier of high speed interconnect IP technology, have partnered to deliver joint PHY plus Media Access Controller (MAC) solutions supporting 40 Gigabit Ethernet, 100 Gigabit Ethernet and Interlaken specifications. The 40/100Gbps Ethernet and Interlaken standards are driving the backbones of next-generation transport networks, data centers and compute farms. The technology combination will allow customers access to unprecedented bandwidth and high scalability, with very high reliability.

The combined solution leverages MoSys' 10Gbps SerDes and Sarance's 40GE and 100GE MAC, Physical Coding Sub-layer (PCS) and Multi Lane Distribution (MLD) IP conforming to the emerging 40GE and 100GE standard using IEEE defined XLAUI (40GE) and CAUI (100GE) interfaces. By teaming up to provide proven interoperability, application notes and direct engineering assistance, MoSys and Sarance enable Ethernet designers to reduce time-to-market, costs and risks when integrating 40GE and 100GE protocols.

"Our combined solution for 40GE and 100GE, which are vital to cloud computing services, will help network service providers and data centers exploit the full potential of high speed Ethernet," said David DeMaria, Vice President of Business Operations at MoSys. "Our customers are now in a strong position to meet the needs of a networking infrastructure rapidly moving to 40GE, 100GE and beyond."

"Our silicon proven IP has been tested by multiple silicon, system and test equipment companies in system labs and validated in field trials running more than one trillion error-free Ethernet frames over live 100GE networks," said Farhad Shafai, Vice President of R&D at Sarance Technologies. "By integrating the technologies from both companies, we are uniquely positioned to accelerate the deployment of products that offer service providers the ever increasing bandwidth they require, as well as simplifying the development of products for data centers that address the explosive bandwidth requiring higher-speed Ethernet."

Information and further details about the integrated 40GE and 100GE solutions are available from both companies. Contact MoSys at www.mosys.com/contact.php and Sarance at www.sarance.com/contact.
