Claim 11:
12. The method according to claim 11, wherein
the first memory includes a first buffer and a second buffer,
the first memory is configured to perform:
a first read operation including transferring first data from the nonvolatile storage region to the first buffer, transferring the first data from the first buffer to the second buffer, and transferring the first data from the second buffer to a memory controller, and
a second read operation including transferring second data from the nonvolatile storage region to the first buffer, transferring the second data from the first buffer to the second buffer, transferring the second data from the second buffer to the memory controller, and transferring third data from the nonvolatile storage region to the first buffer in a period overlapping with a period in which the second data is transferred from the second buffer to the memory controller,

the method further comprises:
causing the first memory to perform the first read operation upon determining not to perform the prefetch operation; and
causing the first memory to perform the second read operation upon determining to perform the prefetch operation.
