Abstract:
To enhance accuracy of counting the number of rewrite cycles in a non-volatile memory that is overwritable. A memory outputs erase information that is information regarding whether or not erase processing has been performed in writing of data in units of pages each including a plurality of memory cells in which data is rewritten by program processing of shifting a memory cell that stores data from an initial state to a data-storing state and erase processing of shifting the memory cell from the data-storing state to the initial state. The number of rewrite cycles is counted by updating the number of rewrite cycles on a basis of the output erase information.

Claim (Index 6):
The memory controller according to  claim 4 , wherein\n the memory outputs the erase information for each of regions obtained by dividing the page into predetermined sizes, the counting-of-number-of-rewrite-cycles determination unit performs the determination for each of the regions, and the number-of-rewrite-cycles management unit updates and retains the number of rewrite cycles for each of the regions, further comprising a number-of-rewrite-cycles output unit that outputs a maximum number of rewrite cycles among the numbers of rewrite cycles of the respective regions in the retained page, as the number of rewrite cycles in the page.
