Abstract
A memory system according to an embodiment of the present invention includes a volatile first storing unit, a nonvolatile second storing unit, a controller that transfers data between a host apparatus and the second storing unit via the first storing unit. The memory system monitors whether data written from the host apparatus in the first storing unit has a specific pattern in management units. When data to be flushed to the second storing unit has the specific pattern, the memory system set an invalid address value that is not in use in the second storing unit to the data.
