    摘要: According to one embodiment, a memory chip, which is connected to a writing device that writes data and to a reading device that reads data, includes: a memory including a first area that is a predetermined data storage area; a second encryption key generating unit that receives second key information stored in the reading device and generates a third key; and a sending unit that transmits, to the reading device, second encrypted data obtained by encrypting data stored in the memory using the third key. The second encrypted data is received by the reading device and is decrypted by using a fourth key that is stored in the reading device and that corresponds to the third key.
