SEMICONDUCTOR DEVICE AND OPERATION TIMING ADJUSTMENT METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor device capable of accurately adjusting timing at which an input circuit captures data.SOLUTION: An interface chip IF has a TSV buffer 52 that serially outputs a plurality of write data items to a core chip CC0 at timing based on a control signal DWCLKTSV. The core chip CC0 includes: holding circuits 70a and 70b that parallelly hold the write data items which are serially supplied from the interface chip IF; a write control timing adjustment circuit 76 that generates a control signal DWCLKTSVOUT according to an internal write command WR; a delay adjustment circuit 75 that delays the timing for supplying the internal write command WR to the write control timing adjustment circuit 76; and an input buffer 71 that sequentially retrieves the plurality of write data items from the holding circuits 70a and 70b at the timing based on the control signal DWCLKTSVOUT.
