Abstract
First and second global input/output lines are twisted between first and second main blocks. First and second SD signal lines in the first main block are respectively arranged adjacent to first and second global input/output lines. First and second SD signal lines in the second main block are respectively arranged adjacent to the second and first global input/output lines. An SD signal supplied for the first or second SD signal line makes noises applied to the first and second global input/output lines identical, so that an influence by the noises is substantially eliminated between the first and second global input/output lines. As a result, the global input/output line is provided with higher resistance to noise without any increase in a layout area.
