A stacked semiconductor device includes a plurality of stacked chips, each having a plurality of elements to receive a signal. At least one first ladder main signal line for receiving the signal is arranged to pass through the chips. At least one second ladder main signal line is arranged to pass through the chips. A plurality of ladder buffers buffer the signal applied from the first ladder main signal line to the second ladder main signal line. The signal is uniformly distributed to the stacked chips using a ladder type circuit network technique. |
