Claim 9:
10. A control method in a memory system, wherein the memory system includes a non-volatile memory including a first memory area and a second memory area, each of the first memory area and the second memory area can be accessed via a plurality of channels, the control method comprising:
writing data of a plurality of clusters into the first memory area via the plurality of channels based on a write command regarding sequential data from a host;
specifying an order in which the data of the plurality of clusters is written based on log information;
generating order information correlating cluster identification information and writing order information based on the specified order;
reading the data of the plurality of clusters from the first memory area based on a read instruction regarding an internal process;
rearranging the read data of the plurality of clusters based on the order information; and
writing the rearranged data into the second memory area via the plurality of channels based on a write instruction regarding the internal process.
