A data input circuit comprises a sensing control unit which delays an internal write command by a predetermined period and generates a sense amplifier enable signal in response to a first clock signal, and a data sensing unit which senses align data and transfers the sensed data to a global line in response to the sense amplifier enable signal, wherein the sense amplifier enable signal is enabled at a time point when the align data is inputted in the data sensing unit.
