Abstract
A semiconductor device has a boosting circuit configured to generate a boosting potential to an output line. An internal circuit is supplied with the boosting potential from the boosting circuit via the output line. A test line is connected to the output line. A control circuit is arranged between the output line and the test line and configured to shut off a current flowing into the test line from the output line during a boosting operation of the boosting circuit.
