Abstract
A content addressable memory device is provided which may include a novel CAM cell structure which reduces the total power dissipated by the CAM and improves the match time for the CAM. The novel CAM cell stnictuire may include a CMOS implemented compare cell and a wide AND gate which combines the match decisions for each CAM cell into a match decision. The CAM cell structure may be implemented in a variety of different CAM devices, including dual port CAM devices, CAM devices with individual bit masking, event co-processors and database co-processors.
