Semiconductor device

摘要

A programmable analog device and an analog device that can retain data even when supply of a power supply potential is interrupted and consumes less power. In a semiconductor device, first to fourth transistors are used as switches in a unit cell including an analog element, and the output of the unit cell switches between a conducting state, a non-conducting state, and a conducting state through the analog element by controlling the potential of a first node where the first transistor and the second transistor are connected and the potential of a second node where the third transistor and the fourth transistor are connected.
