PROBLEM TO BE SOLVED: To provide a semiconductor storage device that can accurately synchronize a strobe signal generated from a clock signal and digital data in a memory controller for inputting and outputting digital data into and from a DDR-SDRAM or the like. SOLUTION: Many output holding circuits 108 are respectively adjacent to every many data output terminals 105, and output delay circuits 112 in n/2 number are adjacent to twos of signal output terminals 106 in n number. A wiring length from the output holding circuits 108 to the data output terminals 105, and a wiring length from the output delay circuits 112 to the signal output terminals 106 are the same, so that delays in digital data transmitted from the output holding circuits 108 to the data output terminals 105 and in an output strobe signal transmitted from the output delay circuits 112 to the signal output terminals 106 can be the same.
