Claim 18:
19. A data storage system comprising:
a main substrate;
a semiconductor device on the main substrate; and
a controller electrically connected to the semiconductor device on the main substrate, wherein:
the semiconductor device comprises:
a semiconductor substrate having a first surface and a second surface opposing each other;
a back side insulating layer below the second surface of the semiconductor substrate;
an external input/output conductive pattern below the back side insulating layer;
a circuit device including a gate electrode and a source/drain region, on the first surface of the semiconductor substrate;
an internal input/output conductive pattern on the first surface of the semiconductor substrate, the internal input/output conductive pattern having at least a portion disposed on the same level as at least a portion of the gate electrode;
a through-electrode structure penetrating through the semiconductor substrate and the back side insulating layer and electrically connected to the internal input/output conductive pattern and the external input/output conductive pattern; and
a memory cell array region disposed on a level higher than the circuit device, on the first surface of the semiconductor substrate,

wherein each of the gate electrode and the internal input/output conductive pattern includes
a lower conductive pattern including a silicon layer, and
an upper conductive pattern.
