PROBLEM TO BE SOLVED: To reduce malfunction of a pass transistor.SOLUTION: A semiconductor device comprises a pass gate circuit having transistors (MP, MW, MC). The transistor MP functions as a pass transistor for connecting a signal line (INL) and a signal line (OUTL). The transistor MW connects a signal line (BL) for inputting a signal setting ON/OFF of the transistor MP and a node SN (gate of transistor MP). In the case where potential of INL is at a high-level when writing high-level potential to the node SN, potential of BL is set at potential higher than normal high-level potential. By doing this, even when potential of the node SN drops due to transition of INL from a high level to a low level, high potential is preliminarily written, the potential drop does not influence an operation of the transistor MP. |
