Abstract
An error detection-correction unit reads system information for operating a system from a first memory and performs error detection-correction processing. A control unit supplies the system information to a host computer in a case where the error detection-correction processing is successful. In addition, the control unit reads a backup of the system information from a second memory that is different from the first memory and supplies the backup of the system information to the host computer in a case where the detection-correction processing fails.
Claims20
A storage control device comprising:
- an error detection-correction unit that reads system information for operating a system from a first memory and performs error detection-correction processing;
- and
- a control unit that supplies the system information to a host computer in a case where the error detection-correction processing is successful, and reads a backup of the system information from a second memory and supplies the backup of the system information to the host computer in a case where the detection-correction processing fails,
- wherein the first memory includes a resistance change type memory and the second memory includes a flash memory,
- wherein the second memory is configured to store a compressed system information as the backup of the system information and the second memory is not provided in the control unit, and
- wherein the first memory is configured to store the system information and the system information is not compressed in the first memory.
