Abstract
In the formation of a stacked IC device formed by stacking IC chips by a plurality of levels, the number of selecting bonding wires connected to select an IC chip on a certain level is reduced. The selecting device of the IC chip on each of the levels is connected to the selecting device on a neighboring level in the form of a chain to form a shift register so that only when a trigger signal is applied to the selecting device, the selecting device sequentially transmits a signal held in itself to the selecting device on the neighboring level.
