ABSTRACT:
A content addressable memory (CAM) device comprising a plurality of CAM blocks and a block control circuit. The plurality of CAM blocks each includes an array of CAM cells to store data words and an array of priority number storage circuits to store priority numbers. Each priority number indicates a priority of a respective one of the data words relative to others of the data words. The block control circuit has an input to receive a class code and circuitry to output a plurality of select signals to the plurality of CAM blocks. Each select signal selectively disables a respective one of the plurality of CAM blocks from participating in a compare operation according to the class code.
