Abstract:
A semiconductor device has: a pull-up circuit connectable to an internal terminal; a pull-down circuit connectable to the internal terminal; and an operation mode switch circuit. The operation mode switch circuit switches an operation mode based on a potential of the internal terminal when the pull-up circuit is connected to the internal terminal and a potential of the internal terminal when the pull-down circuit is connected to the internal terminal.
