Abstract:
Examples disclosed herein relate, in one aspect, to method of searching a content addressable memory (CAM) that stores a plurality of entries. The method may include obtaining a search word corresponding to a matching data word stored in a matching entry of the CAM, where the matching entry may include a plurality of data words. The method may also include determining, based at least on a value of a predetermined bit of the search word, a search mask to mask off any data words within the matching entry other than the matching data word. The method may also determine, based on the search mask and a search key that includes the search word, the address of the matching entry within the CAM.
