Droid Programming

This lack of autonomy was simultaneously a vast asset and a glaring weakness—an asset in terms of obedience and control but a massive drawback in terms of effectiveness. Designers faced a fundamental paradox—make the droids overly intelligent, and they might rebel; yet make the droids not intelligent enough and they would be ineffectual.
Droids tended to be programmed for a specific set of tasks with no ability or knowledge of jobs outside their programmed ones. Droid intelligence however allowed most droids to learn thus granting droids the ability to take on new jobs and tasks. This is one reason why one may not want to do a full memory wipe on a droid. It is possible to do a partial memory wipe but these required more skilled technicians and were often more expensive.
Behavior parameters were often set on droids as to prevent them from harming their owners or others through their behavioral circuitry matrix however due to droid personalities evolving without memory wipes this could change over time. To counteract behavior changes some droids were installed with Behavioral inhibitor chips. These chips were generally only used when a droid seemed to begin to have behavior malfunctions.
A behavioral inhibitor chip was a piece of technology that controlled a droid's behavior. They came in various levels of strictness, depending on the extremity of the droid's behavior.
The behavioral circuitry matrix was the combined mechanical and neutronic subsystems that produced droid behavior. The matrix was split into two modules—the obedience-rational module and the sensory-response module. The obedience-rational module governed the logical and social behavior of the droid while the sensory-response module controlled the droid's systems.
Behavioral circuitry matrix was generally stored in the Droid's Primary Databanks, if a droid were to be given new parts that had no behavioral circuitry matrix then those parts would respond to the already existing and established matrix. This allowed droid parts such as the head to be swapped and the body following the parameters of whatever head was attached.
If a droid had no restraining bolt or Behavioral inhibitor installed and was allowed to go on without a memory wipe a droid would essentially grow and develop it's own personality and identity.
