Abstract
A controller controls a semiconductor memory device including a plurality of memory blocks. The controller may include a controller control unit and a storing unit. The controller control unit compares the number of times of a read of an original memory block among the plurality of memory blocks with a predetermined copy generation reference value, determines whether to generate copy data of original data stored in the original memory block, and generates a command corresponding to the determination. The storage unit stores the copy generation reference value and address information about the original memory block.
