Abstract
A internal voltage generator includes a plurality of voltage level detection units, each configured to detect a voltage level of a corresponding internal voltage terminal, based on a predetermined target voltage level assigned to the corresponding internal voltage terminal, and generate a detection signal, a common internal voltage generation unit configured to generate an internal voltage through a pumping operation in response to the detection signal outputted from the voltage level detection units, and a path multiplexing unit configured to selectively output the internal voltage to one of the internal voltage terminals.
