Memory wipe/Legends

"I'm placing these droids in your care. Treat them well. Clean them up. Have the protocol droid's mind wiped."

- Bail Organa to Raymus Antilles

A memory wipe, also known as a memory flush, was a procedure which totally erased the memory of a droid. All databanks, except for basic factory-installed programming, were "wiped" clean. Most droid owners performed memory wipes regularly in order to prevent the development of personality and thus of independence. A memory wipe was performed with a memory flush unit.

There was evidence, however, suggesting that not performing memory wipes could have beneficial side-effects. One such side effect was that the droid was better capable of infering the wishes of its master, increasing its efficiency and accuracy. Also, droids with accumulated memories were often more effective because of their increased practical knowledge and real-world familiarity. Technicians working on Luke Skywalker's X-wing found that because Skywalker refused to wipe R2-D2's memory that the droid was needed to decipher diagnostics from the X-wing, but at the same time communications between R2-D2 and the ship had greatly improved as time went by.

The periodic application of memory wipes became commonplace sometime after 200 BBY, when a cybersociologist of the Baobab Merchant Fleet accidentally created a personality algorithm that ran rampant as a virus through the droid population.

Bail Organa ordered Raymus Antilles to wipe C-3PO's memory to ensure the true lineage of Leia Organa remained unknown. Years later, but for a similar motive, Owen Lars told Luke Skywalker to wipe the memory of two recently acquired droids&mdash;C-3PO and R2-D2&mdash;in order to keep Luke from finding out about his heritage. The wipe, however, was never performed.

Wedge Antilles had the memories of Mynock - the R5-D2 droid he used with his ship - wiped after finding that in battle situations that the droid's screaming was too much of a distraction. The technicians wiped Mynock's memory and made a number of other improvements, which resulted in the droid being redesignated R5-G8. Wedge then renamed the droid Gate.

During the days of the Old Republic a criminal organization called the Syndicat created a memory-wiping device for Humans. The Syndicat used this device to wipe the memories of the natives of Phindar who defied them, as a punishment. It was destroyed by the natives in the battle that brought the end of the Syndicat in 44 BBY.
