An information processing device includes an internal memory which is capable of performing processing faster than an external memory, and a memory controller which controls data transfer between the internal memory and the external memory. The memory controller controls a first data transfer and a second data transfer. The first data transfer is a data transfer from the external memory to the internal memory, and the second data transfer is a data transfer from the internal memory to the external memory. The second data transfer transfers a part of the data area of the internal memory transferred in the first data transfer, and the data area which is read out in a non-continuous way from the internal memory is transferred in place to the external memory in the second data transfer. |
