Abstract
An address management circuit and method of operation, for use in a communications internetworking device, includes a search engine having first and second search circuits for concurrently searching a network address table for source and destination addresses of a frame received by the communications internetworking device. Memory read cycles of the source and destination address searches are interleaved to allow a memory access to occur during every system cycle to thereby rapidly complete the searches for both the source and destination addresses.
