Claim 19:
20. The data storage system of claim 19, wherein:
the upper conductive pattern is arranged on the lower conductive pattern,
the upper conductive pattern is formed of one of a metal nitride, a metal, and a metal-semiconductor compound, or a combination of at least two thereof,
the through-electrode structure includes a through-electrode and an insulating spacer covering at least a portion of a side surface of the through-electrode,
the through-electrode further includes a portion extending inwardly of the internal input/output conductive pattern,
an upper surface of the through-electrode is disposed on a higher level than a lower surface of the internal input/output conductive pattern and on a lower level than an upper surface of the internal input/output conductive pattern, and
the upper surface of the through-electrode is disposed on a level higher than an upper end of the insulating spacer.
