In this synaptic circuit, a ferroelectric capacitor and a paraelectric capacitor are connected together in series, potential is retained in a serial connection part by the learning signal pulse, and the potential is transmitted by a transmission gate. 強誘電体キャパシタと常誘電体キャパシタを直列接続させ、学習信号パルスにより直列接続部に電位を保持させ、その電位をトランスミッションゲートで伝達するシナプス回路。 - 特許庁
