Zusammenfassung:	According to one embodiment, a storage device includes a plurality of writable non-volatile memory devices, a buffer memory, a memory controller, and a spare non-volatile memory device. The buffer memory temporarily stores write data from a host. The memory controller writes the write data in the buffer memory to the non-volatile memory devices in a distributed manner. The memory controller writes write data in the buffer memory not having been written to the non-volatile memory devices to the spare non-volatile memory device when detecting a power down, and writes the write data having been written to the spare non-volatile memory device to the buffer memory when the power is restored.
