A semiconductor substrate(110) includes a body(102) at least one pair of fins(105a,105b) projected upwardly from the body. A first dielectric(125) is formed on the body to gap-fill a spacer between the pair of fins of the semiconductor substrate. Plural control gate electrodes(155a,155b) are extended by crossing the first dielectric and the pair of fins of the semiconductor substrate, cover at least upper portion of an external wall of the fins, and are insulated from the semiconductor substrate. Plural storage nodes(150a,150b) are disposed between the control gate electrodes and the fins of the semiconductor substrate and insulated from the semiconductor substrate. The control gate electrodes are sequentially formed to become two pairs. The control gate electrodes of the same pair have a first separated distance. The control gate electrodes neighboring the adjacent other pair have a second separated distance greater than the first separated distance.
