An internal voltage generator of a semiconductor device consumes relatively small amount of driving current and generates a stable internal voltage with relatively small voltage level variation. The semiconductor device includes an oscillator configured to generate an oscillation signal in response to an input signal, wherein the oscillation signal oscillates with a first period and oscillates with a second period longer than the first period during a predetermined latter section, and an internal circuit configured to perform a predetermined operation in response to the oscillation signal.
