| Abstract(in English) | Energy harvesting is a key technology to supply power for Internet of Things (IoT) devices. Computing devices for IoTs must operate intermittently rather than continuously, because harvested energy is unstable and small. In this paper, we describe measurement results of a nonvolatile standard cell memory (NV-SCM) and nonvolatile flip-flops (NV-FF) using Fishbone-in-Cage Capacitor (FiCC) suitable for IoT processors with intermittent operations. From simulation results the sequential circuit using nonvolatile storage cells can reduce the energy consumption by 24.3% in a 180 nm CMOS process compared to the volatile circuit when hibernation/normal operation time ratio is 500. NV-SCM and NV-FF are fabricated in a 180 nm CMOS process technology. The area overhead by nonvolatility of a bit cell are 74% in NV-SCM and 29% in NV-FF,respectively. We confirmed full functionality of the NV-SCM and NV-FF. |
