<p>A first-in first-out (FIFO) storage device for storing data including continuous identical values, which is reduced in a required circuit scale and increased in a reading operation speed, and which comprises a memory region (13) provided with a counter unit and a data unit corresponding to a plurality of addresses, a comparison unit (11) for checking whether or not a new input data is identical with an input data one data ahead of the new one, and a write control unit (12) for controlling, based on the checked result by the comparison unit (11), to write the current input data into a new address in the data unit of the memory region (13) when the new input data is not identical with the one-data-ahead input data and for controlling to count up a count value in a one-address-ahead address in the counter unit of the memory region (13) when the two data are identical with other.</p> |
