Abstract

See full text

According to one embodiment, a memory system includes a first nonvolatile memory, a second nonvolatile memory and a controller. The first nonvolatile memory includes a first memory element. The second nonvolatile memory includes a second memory element in which data is able to be written only once. The second memory element stores first key information. The controller receives second key information stored in an information processing apparatus, generates a first key using the first key information and the second key information, and generates a second key using at least the first key. The controller encrypts data, which is to be written into the first nonvolatile memory, with the second key, and decrypts data, which is read from the first nonvolatile memory, with the second key.
