As the technology scales down to the deep submicron domain, the leakage energy in memory devices could contribute to a significant portion of the total energy consumption. Therefore, evaluation of energy consumption including the leakage energy is necessary. In this paper, we investigate the effectiveness of scratch-pad memory on energy reduction considering both the dynamic and leakage energy. The experiments are performed for 65nm, 45nm, and 32nm technologies. The results demonstrate the effectiveness of scratch-pad memory in deep submicron technology. It is also observed that the leakage energy becomes less significant along with the technology scaling.
