MoSys Announces First Shipment and Sample Availability of its Bandwidth Engine IC

SANTA CLARA, Calif.--January 11, 2011 -- MoSys (NASDAQ: MOSY), a leading architect of serial chip-to-chip communications solutions that deliver unparalleled bandwidth performance for next generation networking systems and advanced system-on-chip (SoC) designs, today announced sample availability and the shipment of its first Bandwidth Engine® integrated circuit (IC) devices in December 2010.

For many years the performance of processors in applications such as computing and networking has approximately doubled every 18 months; however, system memory architecture and capability have not kept pace, creating a significant barrier to improving overall equipment performance. The Bandwidth Engine family of ICs represents a breakthrough for next-generation networking systems. The unique architecture of the Bandwidth Engine IC combines MoSys' patented 1T-SRAM® high-density embedded memory with its ultra high-speed 10.3 Gigabits per second (Gbps) SerDes interface (I/O) technology and an arithmetic logic unit (ALU). The Bandwidth Engine family of products delivers unprecedented bandwidth to next generation networking applications enabling up to four times the throughput, two to four times the density, approximately 40 percent lower system power and a system cost savings of up to 50 percent, compared with today’s available alternative solutions.

“In February 2010, we announced our intent to bring to market a revolutionary new networking memory chip architected for use in 40Gbps/100Gbps Gigabit Ethernet routers. In July 2010, we announced the tape-out of Bandwidth Engine, and today I am pleased to announce that we met our goal of sampling by year end 2010,” said Len Perham, President and CEO of MoSys. “This key achievement is a testament to the magnificent execution of our team. Customer and partner interest in Bandwidth Engine continues to be remarkably strong, and we are very excited about the substantial opportunity for the Bandwidth Engine family of ICs to provide a strong foundation for long-term growth and value creation at MoSys.”
