MOS Technology, Inc. (Metal-Oxide Semiconductor) was an American semiconductor manufacturer. It is best known for creating one of the most popular CPUs in history, the 6502 processor. It was the primary CPU of the Commodore 64, the Nintendo Entertainment System (integrated into the Ricoh 2A03), the Apple II, the Atari 2600 and the Atari 8-bit. In 1976, the company was bought by Commodore Business Machines and renamed to CSG (Commodore Semiconductor Group), though its chips still carried the MOS name.

After CBM purchased MOS Technology, they used the company to produce numerous chips used by the various Commodore computers, including several audio chips.
