A 16 X 16 CAM (Content-Addressable Memory) based on improved CAL (Clocked Adiabatic Logic) circuits is presented, which is realized using TSMC 0.18um process. The CAL is a dual-rail logic that operates from a single-phase AC power-clock supply. For a comparison, a conventional CAL CAM has also been designed using TSMC 0.18mm process. Full-custom layouts are drawn, and the net-lists are extracted from their layouts. The post-layout simulations have been performed. The results show that the improved CAL CAM can work very well, illustrating an overall power reduction of 30.8% compared with the conventional CAL CAM for search operation at 100 MHz.
