Patent ID: 7276791

Claim:
An electronic device, comprising: a plurality of mount regions provided in the electronic device, each of said mount regions being electrically interconnected to other of said mount regions; a semiconductor package mounted on each of at least two of said mount regions, each of said semiconductor packages being electrically interconnected to other of said semiconductor packages so that each of said semiconductor packages and being different than said other of said semiconductor packages can implement a desired function in cooperation with said other of said semiconductor packages to which it is electrically interconnected; each of said mount regions being positioned in the electronic device so that each of said semiconductor packages is spaced from adjacent semiconductor packages by a wiring distance, said wiring distance between each adjacent pair of semiconductor packages being about the same; a board; and at least one non-mount region on which no semiconductor package is mounted; said mount regions and said non-mount regions having rectangular shapes of equal size and being alternately arranged in rows and columns on said board to form a matrix pattern.
