PROBLEM TO BE SOLVED: To provide a FIFO memory device which can read data of the same address plural times. SOLUTION: In a FIFO memory device 1, a write pointer 4 writes successively first to Mth line data in a memory circuit 2. First, a read pointer 7 is activated and first read of the first line data is performed, next, a read pointer 8 is activated, second read of the first line data is performed. Thus, read pointers 7, 8 are activated alternately, and read out the first no Mth line data two times respectively.
