PROBLEM TO BE SOLVED: To construct a large capacity FIFO memory device having a required input/output speed without needing a large capacity high-speed memory. SOLUTION: A memory 60 and a disk drive 30 having different data input/output speeds are used to construct an FIFO memory device. An FIFO managing part 40 sets a division ratio on the basis of required memory capacity and the capacity of the memory 60, divides data inputted from an input part 10 on the basis of the division ratio to store the data, connects data read from the memory 60 and the disk drive 30 and sequentially outputs the connected data from an output part 70.
