The data is stored in a plurality of portions of the memory where each portion is defined by a tag. The tag encryption mask indicates an encryption status of each portion of the memory defined by a tag. The communication link is configured to communicatively link the memory to a printer controller when the replaceable printer component is installed in a printing system.
