A semiconductor device may include a decoder for decoding a plurality of internal command signals and outputting a first Y-address enabling signal; a Y-address enabling signal generator for receiving the first Y-address enabling signal and outputting a second Y-address enabling signal having a predetermined enabled period; a multiplexer (MUX) for receiving the first Y-address enabling signal and the second Y-address enabling signal and selectively outputting any one thereof as a Y-address enabling signal; and a MUX controller for controlling the MUX such that the MUX selects any one of the first Y-address enabling signal or second Y-address enabling signal according to an operation mode of the semiconductor device.
