Abstract
The memory controller updates a count number based on a new assignment of a logical block to a physical block, and writes count information in the physical block to which the logical block is newly assigned. The count information is defined by the count number. The memory controller decides, based on the count number and the count information stored in each physical block, whether or not to transfer stored data in a physical block to another physical block.
