PROBLEM TO BE SOLVED: To provide a readout control circuit and a FIFO(First-in First-out) control circuit which can shorten a period of time from the start of write-in to the start of reading. SOLUTION: The readout control circuit 22a is provided with an enable signal generating circuit 21a which generates an enable signal ES by detecting the start of write-in based on a write-in clock CLK<SB>1</SB>at the time of write-in operation and a reset signal generating circuit 6 which outputs a reset signal RS to the enable signal generating circuit 21a by detecting the completion of write-in.
