摘要:
Systems and methods are provided for a content addressable memory. A system includes a common memory module configured to store a plurality of entries, ones of the entries being defined by a string of bits. A first parallel compare logic unit is configured to compare a first lookup key against a plurality of entries stored in the memory module in a first memory operation cycle and to output a match indication indicating a match between the first lookup key and the string of bits of an entry from among the plurality of entries. A second parallel compare logic unit is configured to compare, in the first memory operation cycle, a second lookup key against the plurality of entries stored in the memory module and to output a match indication indicating a match between the second lookup key and the string of bits of an entry from among the plurality of entries.
