Abstract
A process cartridge removably insertable in a body of an image-forming apparatus. The process cartridge has at least one constituent element executing an image formation process, and a non-volatile memory. In the non-volatile memory, data having an identical content are stored at a plurality of mutually spaced locations, the number of which depends on a kind of the data. With respect the locations for the data of an identical content, an address shift amount from one location to another is set according to the kind of the data.
