PROBLEM TO BE SOLVED: To continuously obtain functions of FIFO(first in first out) with respect to plural pairs of data even when reducing areas storing data. SOLUTION: This memory is made so as to obtain a function of FIFO with respect to this string by shifting the string of data to be inputted from a memory M0 to a memory M3 and by reading out the string from the memory M0 while switching back the string. Besides, this memory is made so as to also obtain a function of FIFO with respect to this string by shifting the string of data to be inputted from the memory M3 to the memory M0 and by reading out the string from the memory M3 while switching back the the string. Then, since these two stings of the data are shifted in between the memories M0-M3 while keeping a relation of push-pull with each other, the number of elements of respective strings is sufficient as the necessary number of memories. |
