Droid brain

Droid brains, sometimes referred to as data-brains, a droid processor, cognitive modules, cognitive units, thought processor, or computer brains, were a form of processing computer usually used in droids. They could also be used in starships, and the modified YT-1300 light freighter known as the Millennium Falcon was equipped with three: an R3-series astromech droid's brain, a V-5 transport droid brain and a slicer droid brain. The astromech droid brain is a hybrid of L3-37. The droid brains of the Falcon quarreled endlessly unless they were forced to work together, leaving the ship cantankerous. None of the brains could stand the protocol droid C-3PO, whilst one had a fondness for both romantic gossip and dirty jokes, which the astromech droid R2-D2 provided in large quantities.

Droid brains could also be applied to armor; by doing so, the droid brain defense system had an increased defensive ability.
