Abstract: Memory devices and methods of fabricating the same include a substrate including a cell region and a peripheral circuit region, data storages on the cell region, first bit lines on and coupled to the data storages, first contacts coupled to peripheral transistors on the peripheral circuit region, and second bit lines on and coupled to the first contacts. The second bit lines may each have a lowermost surface lower than a lowermost surface of the data storages.
