Abstract
According to one embodiment, a memory system is connectable to a host. The memory system includes a nonvolatile first memory, a volatile second memory and a controller. The nonvolatile first memory stores translation information. The translation information associates a logical address and a physical address. The volatile second memory stores location information. The location information associates a logical address and a location where the translation information is stored in the first memory. The controller saves a first memory image in the first memory at a first timing, and saves a second memory image in the first memory at a second timing different from the first timing. The first memory image is a part of a memory image of the location information. The second memory image is another part, different form the first memory image, of the memory image of the location information.
