    Abstract: Electronic systems, such as printing systems, often use components that have a memory. The integral memory can be used to store information about the component. In some printing systems this memory includes storing a portion that stores a value indicative of an amount of a consumable that has been used. Discloses is a method and system for updating a memory that is integral to a component within a printing system. The value stored in the memory can be read to determine an amount of a consumable used. Alternatively, when a specific value is stored in the memory the printing system can deactivate the component.
