Abstract(in Japanese) (See Japanese page)
Abstract(in English) We propose a CMOS circuit implementation of a memory circuit for ultralow-power IoT devices based on stochastic computing, utilizing the subthreshold region of MOSFETs. The proposed circuit consists of a bistable system with subthreshold MOSFETs, which randomly generate 0 or 1 signals by applying noise. In addition to this, the probability of the binary output of the proposed circuit can be varied by using a floating-gate MOSFET as an analog memory. Through simulation, the bistability of the proposed circuit and the probability change characteristics by the floating-gate MOSFET are confirmed.
