A personality chip is an integrated circuit containing data information of an android. Iko's unique personality chip evolved into something near human, though her programming had always been glitchy. In Winter, Cinder reveals that Linh Garan stored the blueprints for the bioelectricity security system. [citation needed]
Function[]
Personality chips in androids are replaceable & reusable elsewhere as they are present in any sort of escort-droid. Iko is a prime example of a reusable personality chip that can be preserved with memories of past and or recent events. In Scarlet, Iko's personality chip was inserted into the Rampion as she acted as the ship's auto-control system.
