In a stacked integrated circuit device, there are two components, one in a first of the die and another in a second of the die. Each of the components is provided with two output connections, one leading above and one leading below the die, and two input connections, one leading above and one leading below the die, either of the two die. As a result of the redundancy, both die may be used in either position in the stacked structure. If either of the die is used as the top die, it sends data on its second output path and receives data on its second input path. On the other hand, when one of the die is used as the bottom die, it sends data on its first output path and receives data on its first input path. In this way, the same design may be used for the connections between each of the die.
