Storage control device, a storage control program, and a storage control method

PROBLEM TO BE SOLVED: To suppress a decrease in reading performance due to overhead of a command response.SOLUTION: A storage part 1a stores management information 1c for managing presence/no presence of data writing in a first storage region 4a. A control part 1b updates the management information 1c so as to cause a first storage region 4e to be a range including a second storage region 4c with an end address 4b of the first storage region 4a as an end address 4d of the second storage region 4c in the case of writing data to be written and a check code corresponding to the data to be written in the second storage region 4c being a continuous storage region while including the next address 4f of the end address 4b of the first storage region 4a specified from the management information 1c. Also, the control part 1b reads a check code corresponding to data to be read together with the data to be read in the case of reading the data to be read from the inside of the storage region 4e specified from the management information 1c.SELECTED DRAWING: Figure 1
