PROBLEM TO BE SOLVED: To provide a semiconductor storage device capable of preventing conflict of the selection period of a refresh word line with the selection period of a read/write word line. SOLUTION: The semiconductor storage device is provided with a cell array 100 including a plurality of memory cells needed to be refreshed for holding storage, and a means 126 for performing control so as to delay a read/write operation in the cell array by at least one clock cycle when a read/write request is input at a clock cycle sequel to the clock cycle of a refreshing operation, and to start a read/write operation in the cell array after completion of refreshing.
