Abstract
A control device includes: a management information generation unit configured to generate or update logical-physical block address management information with respect to either data to be written to a non-volatile memory or data which has been already written in the non-volatile memory, the logical-physical block address management information indicating association between a logical block address and a physical block address on the non-volatile memory; and an access control unit configured to, during write of the data to the non-volatile memory, control write of the data as well as the logical-physical block address management information to a physical write unit of the non-volatile memory.
Claims9
A control device comprising:
- a management information generation unit configured to generate or update logical-physical block address management information with respect to either data to be written to a non-volatile memory or data which has been already written in the non-volatile memory, the logical-physical block address management information indicating association between a logical block address and a physical block address on the non-volatile memory;
- and
- an access control unit configured to, during write of the data to the non-volatile memory, control write of the data as well as the logical-physical block address management information to a physical write unit of the non-volatile memory.
A storage device comprising:
- a non-volatile memory;
- a management information generation unit configured to generate or update logical-physical block address management information with respect to either data to be written to a non-volatile memory or data which has been already written in the non-volatile memory, the logical-physical block address management information indicating association between a logical block address and a physical block address on the non-volatile memory;
- and
- an access control unit configured to, during write of the data to the non-volatile memory, control write of the data as well as the logical-physical block address management information to a physical write unit of the non-volatile memory.
A storage control method comprising:
- generating or updating logical-physical block address management information with respect to either data to be written to a non-volatile memory or data which has been already written in the non-volatile memory, the logical-physical block address management information indicating association between a logical block address and a physical block address on the non-volatile memory;
- and
- during write of the data to the non-volatile memory, controlling write of the data as well as the logical-physical block address management information to a physical write unit of the non-volatile memory.
