Abstract
According to one embodiment, a memory system includes 1st-5th sub-memory regions and a controller, the controller being configured to: calculate a 1st voltage of the 1st sub-memory region in 1st processing; calculate a 2nd voltage of the 4th sub-memory region in 2nd processing; before the 1st processing, use a 3rd voltage when reading the 1st and 2nd sub-memory regions, and the 4th and the 5th sub-memory regions, and use a 4th voltage of the 3rd sub-memory region when reading the 3rd sub-memory region; use the 1st voltage when reading the 1st sub-memory region, use a 5th voltage calculated by using the 1st voltage when reading the 2nd, the 4th, and the 5th sub-memory regions, use a 6th voltage calculated by using the 2nd voltage when reading the 2nd and the 5th sub-memory regions.
