Semiconductor device with component circuits under symmetric influence of undesirable turbulence

DETAILED DESCRIPTION It is therefore an important object of the present invention to provide a semiconductor memory device the component elements of which is less liable to have influences of other component elements.
It is also important object of the present invention to provide a semiconductor device the layout of which prevents the component elements from the influences of the other component elements.
To accomplish these objects, the present invention proposes to arrange the component elements in a symmetric manner with respect to an influence source.
In accordance with the present invention, there is provided a semiconductor device fabricated on a semiconductor substrate and having a plurality of component circuits of an integrated circuit and at least one component conductive strip operative to propagate a first electric signal, one of the component circuits comprising a) a first pair of component elements operative to produce a second electric signal and the complementary electric signal thereof and arranged in such a manner as to be substantially equivalent in an electrical influence of the component conductive strip to each other, and b) a second pair of component elements operative to produce a third electric signal and arranged in such a manner as to be substantially equivalent in the electric influence of the component conductive strip, the first pair of the component elements are different in the electric influence of the component conductive strip from the second pair of the component elements.
