| Abstract(in English) | In recent years, with the spread of the Internet of Things (IoT) and mobile devices, low power consumption of processors is mandatory to extend their battery life. In this paper, we present an experimental study of a FiCC (Fishbone-in-Cage Capacitor) type nonvolatile flip-flop (NV-FF) suitable for IoT processors with intermittent operation. The NV-FF was fabricated in a 180nm CMOS process technology. The area overhead due to the nonvolatility of bit cells was 29%. We confirmed the operation of the NV-FF at 10MHz. The data retention time was about 155 minutes when the writing time to the nonvolatile memory was 0.1 seconds and the reading voltage was set to 1.4V. Assuming 5 minutes operation and 55 minutes hybernation time per hour, the simulation results show that the proposed nonvolatile resister file can reduce 29.36% of energy consumption compared to a conventional register file. |
