Abstract
A memory controller includes a layout setter and an access processor. The layout setter performs setting of data placement to be applied to multiple channels at the time of parallel data transfer between the memory controller and the flash memory using the multiple channels. The access processor performs, in performing access processing for data on the flash memory, the parallel data transfer to/from the flash memory using the data placement for the multiple channels set by the layout setter. In placing user data and parity data included in the data, the layout setter sets the data placement for the multiple channels to allow, in the multiple channels, second placement regions where the parity data are placed to be collectively placed forward or backward relative to first placement regions where the user data are placed, along an order of access at the time of the parallel data transfer.
