Abstract
A leakage compensation content addressable memory (CAM) circuit includes at least one CAM cell configured to store a bit value, and at least one compensation CAM cell configured to store the bit value of the CAM cell and to cancel leakage current of the CAM cell. The leakage compensation CAM circuit further includes at least one main bit line driver coupled to bit lines of the CAM cell to supply output to the bit lines of the CAM cell, at least one compensation bit line driver coupled to bit lines of the compensation CAM cell to supply output to the bit lines of the compensation CAM cell, and at least one word line driver coupled to word lines to supply output to the word lines of the CAM cell and the compensation CAM cell.
