Abstract

See full text

According to one embodiment, when data is to be written to a first physical storage location that is designated by a first physical address, a memory system encrypts the data with the first physical address and a first encryption key, and writes the encrypted data to the first physical storage location. When the encrypted data is to be copied to a second physical storage location, the memory system decrypts the encrypted data with the first physical address and the first encryption key, and re-encrypts the decrypted data with a second encryption key and a copy destination physical address indicative of the second physical storage location.
