  • Semiconductor memory device having sub dummy bit line and sub dummy word line
    Patent number: 5886939
    Abstract: A semiconductor memory device accurately reads out data from a normal unit cell when a short bridge occurs between the normal unit cell and a dummy unit cell. A sub dummy bit line pair DBL/DBLB is interposed between a sub normal bit line and a sub word line driver region (or a strap region). A direct contact (DC) between the dummy unit cell and a sub dummy bit line is eliminated. A data storage capacitor of the dummy unit cell normally connected to a sub dummy bit line DBLB by way of a buried contact is also removed. Thus, operational errors caused by short bridges created between normal and during unit cells are eliminated.
