Abstract
OS 트랜지스터의 소스 또는 드레인과, OS 트랜지스터의 게이트를 접속하는 노드에, 복수의 전위의 분포를 유지한다. 상기 노드의 전위는, 용량 결합에 의하여 전위를 변동시킴으로써, 게이트가 접속된 OS 트랜지스터의 도통 상태를 제어하여, Si 트랜지스터의 게이트의 전위를 변화시키는 회로 구성으로 한다. Si 트랜지스터의 게이트의 전위는, 용량 결합에 의한 전위의 변동에 의하여 양으로 변동되고, 별도로 제공된 트랜지스터에 의하여 음으로 변동된다. Si 트랜지스터를 흐르는 전류값의 변화를 검출함으로써, 기록된 데이터를 판독하는 구성으로 한다.
