Information storage and processing media used aboard starships circa 2329, and in general usage since around 2349. The chips are composed of a linear memory crystal material and are often mounted in wall racks containing dozens or hundreds of the devices.
Isolinear chips replaced the duotronic system previously in use on Federation starships.
In 2367, while under Romulan mind control, Chief Engineer La Forge altered several chips to covertly beam weapons via cargo transporter to the planet Krios, and to erase all record of the beaming afterward.
