Abstract
A three-dimensional semiconductor device includes a vertical channel pattern on the substrate, a plurality of cell gate patterns and a select gate pattern stacked on the substrate along the sidewall of the vertical channel pattern, a charge storage pattern between the vertical channel pattern and the cell gate pattern and a select gate pattern between the vertical channel pattern and the select gate pattern. The select gate pattern has a different work function from the cell gate pattern.
