Abstract:
In one embodiment, multiple content-addressable memory entries are associated with each other to effectively form a batch content-addressable memory entry that spans multiple physical entries of the content-addressable memory device. To match against this content-addressable memory entry, multiple lookup operations are required—i.e., one lookup operation for each combined physical entry. Further, one embodiment provides that a batch content-addressable memory entry can span one, two, three, or more physical content-addressable memory entries, and batch content-addressable memory entries of varying sizes could be programmed into a single content-addressable memory device. Thus, a lookup operation might take two lookup iterations on the physical entries of the content-addressable memory device, with a next lookup operation taking a different number of lookup iterations (e.g., one, three or more).
