ABSTRACT:
A method and apparatus for simultaneously performing a plurality of compare operations in a content addressable memory (CAM) device. For one embodiment, the CAM device includes first and second memory cells to store first and second data, and first and second compare circuits coupled respectively to first and second match lines. The first compare circuit has a first input coupled to the first memory cell, a plurality of second inputs to receive first comparand data, and a third input coupled to the second memory cell. The second compare circuit has a first input coupled to the first memory cell, a plurality of second inputs to receive second comparand data; and a third input coupled to the second memory cell.
