Saiyed Atiq Raza had founded NexGen, which was acquired by

AMD Advanced Micro Devices, Inc. (AMD) is an American multinational semiconductor company based in Santa Clara, California, that develops computer processors and related technologies for business and consumer markets. While it initially manufactur ...

in 1996. Raza was AMD's president and chief operating officer in the late 1990s after the NexGen acquisition. He left AMD in 1999 and founded Raza Microelectronics, Inc. in 2002. In 2003, SandCraft Inc folded, and Raza acquired the rights to its intellectual property. Behrooz Abdi became president and CEO in November 2007, and Raza Microelectronics changed its name to RMI Corporation in December 2007. In January 2008 Raza settled with the US Securities and Exchange Commission over an allegation of insider trading during 2006. RMI was not affiliated with Foundries Holdings, LLC, formerly known as Raza Foundries, Inc. Most of RMI's revenue came from its multi-core processor product line, which had major customers from China including Huawei, ZTE, and H3C. The China business of RMI was built from scratch by its co-founder Sunny Siu. In 2008, RMI merged with NetLogic Microsystems, which was acquired by
