Abstract
A controller of a memory system executes a first operation on storage regions. The first operation includes (i) acquiring first data based on comparison between a determination voltage and a threshold voltage of each memory cell in a first storage region; (ii) calculating a first fail-bit count of the first data; and (iii) executing or skipping a second operation based on the calculated first fail-bit count. The second operation includes (i) acquiring the second data based on comparison between the determination voltage and the threshold voltage of each memory cell in the first storage region; (ii) calculating a second fail-bit count of the second data; and (iii) updating the determination voltage based on the second fail-bit count.
