Patent ID: 7795943

Claim:
An integrated circuit device, comprising: multiple first circuit elements arranged in a first integrated circuit area; a signal distribution circuit that has multiple drive circuits connected in the form of a tree structure and that distributes a common signal that is input to the starting point of said tree structure to each of the multiple first circuit elements through the same number of levels of drive circuits; wherein at least some of the drive circuits of the tree structure are arranged one each in each of multiple second integrated circuit areas into which the first integrated circuit area is divided to include approximately the same number of the first circuit elements, and the common signal is supplied to the first circuit elements included in the second integrated circuit area where they are arrange; and wherein the second integrated circuit areas are subdivisions wherein a higher-order section area is divided into multiple lower-order section areas with section lines that extend longitudinally or laterally in the first integrated circuit areas, and subdivision to divide the higher-order section areas is repeated so that said multiple lower-order section areas include approximately the same number of the first circuit elements.
