Abstract
A semiconductor memory device is provided which includes a voltage detecting unit configured to compare a target voltage level with a fed-back internal voltage to output a detection signal in a normal mode, a driving unit configured to selectively drive an internal voltage terminal to a first or second power supply voltage according to an operation mode in response to the detection signal, and an enable control unit configured to control the driving unit in response to a control signal corresponding to the operation mode.
