Abstract
A semiconductor integrated circuit device may include a first region, a second region, a pad structure and an electrostatic discharge (ESD) connection. The first region may be positioned adjacent to a semiconductor substrate. An ESD protection circuit may be integrated in the first region. The second region may be stacked on the first region. A plurality of memory cells may be formed in the second region. The pad structure may be arranged over the second region to receive an external voltage. The ESD connection may include a plurality of lower conductive wirings in the first region. At least one of the lower conductive wirings may be electrically connected with the ESD protection circuit. The at least one of the lower conductive wirings may be drawn to a portion corresponding to the pad structure.
