An object of the present invention is to provide a memory controller that can perform a series of data write operations so as to complete the data writing at high speed. A memory controller includes means for dividing the physical blocks into a plurality of groups, means for forming a plurality of virtual blocks by virtually combining a plurality of physical blocks each of which belongs to a different group, and means for assigning adjacent host addresses to different physical blocks belonging to the same virtual block. Thus, when a host computer issues a request to access the plurality of successive host addresses, the physical blocks to be accessed are different physical blocks. Since the physical blocks to be accessed can therefore operate independently, a series of operations can be performed in parallel.
