Abstract
A semiconductor integrated circuit includes a plurality of semiconductor chips stacked in a multi-layer structure; a correction circuit in each semiconductor chip configured to reflect a delay time corresponding to the position of the chip in the stack into an input signal to output to each semiconductor chip; and a plurality of through-chip vias formed vertically through each of the semiconductor chips and configured to transmit the input signal to the semiconductor chip.
