Abstract: A logic circuit, or method using the same, may include a memory storing (i) a plurality of partition groups, each partition group including a plurality of partitions, and (ii) a partition map defining an address and access mode for each of said partitions, defining different access modes for at least some of the partitions. The plurality of partition groups may comprise (i) a general use partition group including a first consumable level counter; (ii) a second use partition group including a second incrementally updatable consumable level counter; and (iii) a guide partition group including a use indicator to indicate which of the first and second consumable level counters to use.

Abstract: Reprocessing of a replaceable supply component may include receiving from an encoding device and using an interface communicatively coupled to the encoding device, a request blob to reprocess a replaceable supply component. The method may include in response to cryptographically verifying the request blob, extracting from the request blob, a supply identifier and raw supply data. The method further includes using the supply identifier and raw supply data, generating a reprocess structure to append or amend original manufacturing data for the replaceable supply component, and providing a response blob to the encoding device, to designate the replaceable supply component as a reprocessed supply component.
