N2 - A new mismatch-dependent low-power technique is presented for content-addressable memories (CAMs). With a novel shadow match-line voltage-detecting scheme, the word circuits realize fast self-disable of the charging paths in case of mismatches. Since the majority of CAMs words are mismatched, a significant power is reduced with a high search speed. Simulation results show the proposed 256-word × 144-bit ternary CAM, using 0.13-μm 1.2-V CMOS process, achieves 0.51 fJ/bitsearch for the word circuit with less than 900 ps search time. The achievement illustrates a 77% energy-delay-product (EDP) reduction as compared to the speedoptimized current-saving scheme.
