<p>PROBLEM TO BE SOLVED: To provide a semiconductor device that can increase cycle time under the restriction of chip size where an MPU(micro processing unit) and a DRAM as a secondary cache memory are mounted on the same chip. SOLUTION: A semiconductor device is provided with an MPU part 40 that is provided on a chip and outputs a clock signal 52 and an address signal 55, a DRAM part 70 that is provided on the chip and inputs the clock signal 52 and the address signal 55 that are outputted from the MPU part 40, a plurality of address registers 75 and 75 for latching the address signal 55 in response to the clock signal 52, and a plurality of address delay correction means 77 that are provided at each prestage of the plurality of address registers 75 and 75, and keep the address signal propagation delay time from the time when an MPU part 40 outputs the signal to the time when the plurality of address registers 75 and 75 input it within each specific range.</p> |
