PURPOSE: A layout method of a global signal line is provided to increase the layout area efficiency in a semiconductor memory device by distributing global signal lines through the use of a peripheral circuit region or a region adjacent to a peripheral circuit region. CONSTITUTION: A layout method of a global signal line comprises the steps of: arranging some global signal lines(GIO) in a peripheral circuit region; and distributing and arranging the rest one in a certain region which is identical to a layer of the peripheral circuit region, wherein global signal lines are arranged at the peripheral circuit region. |
