MoSys, Inc. Earns ISO 9001:2008 Certification

Company Meets International Standards for the design, development, sale and distribution of high bandwidth memory-based semiconductor devices

SANTA CLARA, Calif.-- January 17, 2012 -- MoSys (NASDAQ: MOSY - News), a provider 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 that it has earned ISO 9001:2008 certification from TUV America.

The ISO 9000 series standards are internationally recognized quality management system requirements developed by the International Organization for Standardization (ISO). ISO 9001, the most comprehensive standard in the ISO 9000 series, covers design, development and manufacturing systems. Registration to the prestigious international standards ensures that the company maintains the proper procedures and processes for a complete quality system.

“ISO 9001 certification offers real strategic value, especially when aligned with corporate goals and objectives,” stated Phil Frierson, Director of Quality Assurance and Reliability for MoSys. “Establishing a quality management system through which we consistently comply with requirements while continually improving on MoSys product quality is a demonstration to our customers of our commitment to building quality into the systems they bring to market.”

MoSys began the registration process in 2010. As part of the process, TUV performed an on-site assessment, examination of documented procedures and a survey of the company's overall operations. To determine continued compliance with ISO 9001, TUV will periodically conduct routine audits of MoSys’ operations.

“Achieving ISO 9001 certification is a significant milestone in MoSys’ evolution as a fabless semiconductor company,” said Len Perham, President and CEO of MoSys. “With the right systems in place, MoSys can focus its efforts on developing and delivering products that offer our customers the world-class standard of quality they have a right to expect.”
