Abstract
A content addressable memory (CAM) system configured for reduced power consumption and increased speed includes a plurality of bit cells implementing a stacked architecture. Each bit cell comprises a pair of stacked storage elements in a first column and a compare circuit, coupled to the pair of stacked storage elements and a matchline of the CAM system, situated in a second column. The stacked architecture results in a reduced matchline length, thereby reducing CAM system power consumption and increasing CAM system speed. Further, a content addressable memory (CAM) system configured for reduced power consumption and increased speed includes storing encoded data in a pair of stacked storage elements.
