"Acquiring a CEO with Chris? excellent qualifications is a real coup for AMIS," AMI board member Dipanjan Deb, said in a statement. "Her outstanding relationships with ASIC customers throughout the industry ? including some existing AMIS customers ? will be a tremendous asset for AMIS immediately and in the future."
King will start at AMI on Sept. 10.
An IBM spokesman confirmed King is leaving the company's chipmaking arm but did not offer more details.
AMI was founded in 1966 and acquired last year by Francisco Partners and Citicorp Venture Capital, according to the company's Web site. AMI specializes in a type of custom chip known as application-specific integrated circuits (ASICs). IBM is also known for its ASICs business.
At IBM, King reported to John Kelly, general manager of IBM's Technology Group, which includes its chipmaking unit.
King's departure was earlier reported by the online edition of the Wall Street Journal.
