Abstract
A semiconductor device includes a plurality of stacked dies electrically connected with each other. Each of the stacked dies includes a data path, a strobe path, a stack information generation circuit, and a delay control circuit. The data path transmits a data signal. The strobe path transmits a data strobe signal. The stack information generation circuit generates stack information representing a number of the dies. The delay control circuit controls a delay time of at least one of the data path and the strobe path based on the stack information.
