Abstract
A CAM match detection circuit that maintains established levels of accuracy while greatly reducing the amount of power dissipated is disclosed. Rather than allowing the Matchline 185 voltage to swing between a precharge voltage level of VDD and ground, the Matchline voltage is restricted to swinging between a reduced precharge voltage level (i.e., a voltage level lower than VDD) and ground. Further, a source of a p-type transistor that makes up one transistor in each pair of series connected transistors is coupled to the Matchline thereby further reducing the Matchline swing voltage and the overall power dissipation of the match detection circuit.
