Patent ID: 7716393

Claim:
A system, comprising: a first integrated circuit (IC) having a center and comprising a first half of a switch, a first corner, a second corner adjacent to the first corner, a first proximity I/O communication (PIOC) region, and a second PIOC region, wherein the first PIOC region is disposed in the first corner and the second PIOC region is disposed in the second corner in orientations that differ by 90 degrees; a second IC having a perimeter and comprising a third corner and a second half of the switch, wherein the first IC is configured to communicate with the second IC in a first position using proximity I/O communication and in a second position using proximity I/O communication, wherein the first IC rotates 90 degrees about the center to move from the first position to the second position, wherein the first corner overlaps the third corner in the first position, wherein the second corner overlaps the third corner in the second position, and wherein the center is outside the perimeter in the first position and in the second position; and a central processing unit (CPU) operatively connected to a memory unit using the first IC and the second IC.
