Abstract
Included are a flash memory onto which user data and parity data are recorded, an external interface unit which receives a first write command for instructing recording of the user data onto the flash memory, and a block managing unit which manages management information indicating whether parity data is valid or invalid. When the user data related to the first write command received through the external interface unit is recorded onto the flash memory, the block managing unit updates the management information so as to indicate that the parity data corresponding to the user data is invalid.
