Abstract
A method of controlling a content addressable memory (CAM) device. A data structure is generated that specifies (i) a prioritized set of rules and (ii) storage locations within the CAM device for one or more match clauses of each of the rules. A new rule having a specified priority is recorded in the data structure. Candidate storage locations within the CAM device are identified within the CAM device for the match clauses of each of the rules having a lower priority than the new rule. The candidate storage locations are compared with the storage locations specified by the data structure. Each match clause for which the candidate storage location does not match the specified storage location is stored in the CAM device.
