Oak Technology was an American supplier of semiconductor chips for sound cards, graphics cards and optical storage devices such as CD-ROM, CD-RW and DVD. It achieved success with optical storage chips and its stock price increased substantially around the time of the tech bubble in 2000. After falling on hard times, in 2003 it was acquired by Zoran Corporation. Oak Technology helped develop the ATAPI standard and provided the oakcdrom.sys CD-ROM driver that was ubiquitous on DOS-based systems in the mid-1990s.
