    • An integrated circuit device for processing an access control list. The integrated circuit device includes a first content addressable memory (CAM) including a plurality of CAM blocks to generate respective match indices, each match index indicating a storage location within the corresponding CAM block of an entry that matches a search key. The integrated circuit device further includes a plurality of memory arrays to receive the match indices from the CAM blocks and to output respective lookup values from storage locations indicated by the match indices, each lookup value including information that indicates an action to be taken with respect to a packet used to obtain the search key and information that indicates a priority of the action relative to actions indicated by information in others of the lookup values.
