Silicon Motion Technology Corporation, stylized as SiliconMotion is an American-Taiwanese company involved in developing NAND flash controller integrated circuits (ICs) for solid-state storage devices. The company claims to have supplied more NAND flash controllers than any other company, over five billion from 2006 through 2016.[1] They are found in commercial, enterprise, and industrial applications ranging from SSDs, eMMCs, memory cards, and USB flash drives.[2]

Silicon Motion purchased Shannon Systems which added PCI Express solid-state drives for the Chinese data center market to its portfolio.[3] Controllers are marketed under the “SMI” brand, enterprise-grade SSDs under the "Shannon Systems" brand.


Silicon Motion Technology Corporation was formed as the combination of Silicon Motion, Inc., which was established in 1995 in Silicon Valley in the United States, and Feiya Technology Corporation, which was founded in 1997 in Taipei, Taiwan. At the time, mobile graphic chips were the main product of Silicon Motion and NAND controllers were the main products of Feiya Technology Corporation. In 2002, Concord Asia Capital (now known as Concord Venture Capital Group), mediated the merger of the two companies which was completed in August 2002.[4] In 2005 the combined company was renamed Silicon Motion Technology Corporation and began listing on the NASDAQ stock market under the SIMO ticker symbol.
