PURPOSE: A three dimensional semiconductor memory device and a fabricating method thereof are provided to minimize the resistance increase of a first string selector gate by contacting a first supplement conductive pattern to one side of the first string selector gate. CONSTITUTION: A laminated structure includes first string selector gates(SSG1) which are separated to side. A vertical active pattern consecutively passes through the first string selector gate and cell gates(CG). The cell gates are laminated under the first string selector gate.
