A turbo decoder includes a plurality of element decoders, a memory section that stores element decoded results in matrix-patterned memory spaces, and a memory controller that writes the element decoded result of each of the element decoders in a row or column direction in the matrix-patterned memory spaces with addresses belonging to different rows being specified as writing start addresses, and reads them in the column or row direction with the addresses belonging to different rows being specified as reading start address. As a result, conflict of accesses to the memory required for an interleaving process and a deinterleaving process to be executed at the turbo decoding step can be avoided.
