A device and a method for aligning phase are provided to remove an error accumulated in phase alignment, shorten a phase alignment time remarkably, and offer economical efficiency and easy usage with the reduced number of phase aligners by using a logical gate and a deskew unit. A plurality of drivers(DR1-DRn) output a test signal. A logical gate(120) such as an OR gate receives and composes the test signals of the drivers. A deskew unit(130) delays the composed signal as much as a predetermined delay value. Plural comparators(CP1-CPn) measure a phase delay value by receiving the test signals and a delay signal, and comparing the matched signals, and align the remaining signals to the signal having the biggest phase delay value among the phase delay values. The drivers output a normal signal according to the signal having the biggest phase delay value among the phase delay values.
