Abstract
A semiconductor device resistant to a high temperature with low power consumption is provided. The semiconductor device includes a first and a second circuit, a first and a second cell, and a first and a second wiring. The first cell includes a first transistor, and the second cell includes a second transistor. The first and the second transistor operate in a subthreshold region. The first cell is electrically connected to the first circuit through the first wiring, the first cell is electrically connected to the second circuit through the second wiring, and the second cell is electrically connected to the second circuit through the second wiring. The first cell sets a current flowing through the first transistor to a first current and the second cell sets a current flowing through the second transistor to a second current. At this time, a potential corresponding to the second current is input from the second wiring to the first cell. Then, a third current flows from the second circuit to change a potential of the second wiring, whereby the first cell outputs a fourth current corresponding to the amount of the potential change and the first current.
