Abstract
Disclosed here in is a flash memory device and a method of fabricating the same. In accordance with one aspect of the invention, a flash memory device includes first contact plugs formed over a semiconductor substrate between gate patterns. Second contact plugs are formed over the semiconductor substrate between gate patterns and disposed alternately with the first contact plugs. The second contact plugs having a height greater than the first contact plugs. First and second conductive pads are connected to the first contact plugs. First and second pad contact plugs are formed on extended edge portions of the first and second conductive pads. First bit lines are connected to the first and second pad contact plugs, and second bit lines are connected to the second contact plugs.
