A memory system includes a non-volatile memory, a compressor capable of compressing data, an encryptor which encrypts data, a decryptor which decrypts data, and a data flow controller. The data flow controller is configured to perform first and second processes. In the first process, the data flow controller causes the encryptor to encrypt user data received from a host in a non-compressed state, and causes the encrypted user data to be written into the non-volatile memory via the second area. In the second process, the data flow controller causes the encrypted user data to be read out from the non-volatile memory, causes the decryptor to decrypt the encrypted user data, causes the compressor to compress the decrypted user data, causes the encryptor to encrypt the compressed user data, and causes the encrypted and compressed user data to be written into the non-volatile memory. |
