ABSTRACT:
A semiconductor apparatus includes a voltage unit which supplies a down voltage produced at a node, the voltage unit having a plurality of resistors connected in series between a power supply line and a grounding line, the node being a connection point between the plurality of resistors. A backup unit pulls up the node of the voltage unit when a voltage at the node is below a lower limit of the down voltage, so that the voltage at the node increases to the lower limit, and pulls down the node of the voltage unit when the voltage at the node is above an upper limit of the down voltage, so that the voltage at the node decreases to the upper limit. A control unit sets the backup unit in one of an active state and an inactive state in response to a control signal.
