Abstract
According to an embodiment, a content addressable memory (CAM) device (104) may be capable of executing a “restricted” search operation. A restricted search operation (an “explore” or “search beyond” operation) may compare only a portion of the CAM entries to a search key device. Preferably, a restricted search operation may restrict searches to entries having an index value greater than a received search index value.
