PROBLEM TO BE SOLVED: To provide a turbo decoding device and communication device capable of suppressing the amount of memories to be packaged. SOLUTION: The turbo decoding device 100 includes: a memory unit 101 that stores data in an interleaving process performed in a process of decoding a coded signal encoded with a turbo code; and an access unit 102 that accesses the memory unit to read and write the data. The memory unit includes a plurality of memory circuits and is formed as one memory space by coupling the plurality of memory circuits. Furthermore, the memory circuit functions as a first bank configuration by which a first capacity is assigned to each bank or a second bank configuration by which a second capacity is assigned to each bank in accordance with a combination of the memory circuits. Moreover, the access unit selects by which of the first bank configuration and the second bank configuration the memory unit functions in accordance with a communication method of a coded signal and accesses the memory unit in accordance with the selected bank configuration.
