Isolinear optical chips (or just isolinear chips) were an advanced form of computer chip, utilized as an information storage device or for the operational control of various forms of computer technologies.

They eventually replaced the less efficient duotronic enhancers about forty years prior to 2369. After which time, they were used to enable warp drive in Galaxy-class vessels, store memory in Starfleet PADDs, and were a primary component of Danube-class runabout computers.
