According to one embodiment, a storage apparatus includes a first nonvolatile storage module, a second nonvolatile storage module, and an error checking and correction module. The first nonvolatile storage module undergoes a destructive read when data is read from it. The second nonvolatile storage module stores the address data representing the storage location in the first nonvolatile storage module at which data to be read is stored. The error checking and correction module checks for and corrects an error in the data stored at the storage location in the first nonvolatile storage module which is represented by the address data stored. The error checking and correction module writes the corrected data back into the first nonvolatile storage module.
