Disclosed are a spin logic device based on spin-charge conversion and a spin logic array using the same. A reconfigurable spin logic array according to an exemplary embodiment of the present invention may include: an input terminal receiving at least three current signals; a plurality of wires transmitting the current signal in connection with the input terminal and including a horizontal wire and a vertical wire which cross each other; a first gate array in which at least one first majority gate connected to the input terminal through the wires and implemented based on the spin logic device is arranged; and a second gate array in which at least one second majority gate connected to the first gate array through the wires and implemented based on the spin logic device is arranged.
