Abstract
A memory control device 100 of the present invention includes a data storage processing unit 101 that stores, in an additional data area that is an area for storing additional data in memory-stored data including compressed data and the additional data to be stored in a memory, an error correcting code of the compressed data and compression information representing the degree of compression of the compressed data, and a read processing unit 102 that controls readout of the memory-stored data on the basis of the degree of compression represented by the compression information in the additional data area of the memory-stored data, when reading out the memory-stored data from the memory.
Claims11
A memory control method comprising:
- storing additional data in an additional data area of memory-stored data of a memory including compressed data, the additional data including an error correcting code of the compressed data and compression information representing a degree of compression of the compressed data;
- and
- when reading out the memory-stored data from the memory, performing a readout process a number of times based on the degree of compression represented by the compression information in the additional data area, wherein
- the number of times that the readout process is performed is determined when reading out the memory-stored data from the memory on a basis of a data capacity before compression, a read capacity of one readout process, and the degree of compression represented by the compression information in the additional data area.
A memory control device comprising:
- at least one memory configured to store instructions;
- and
- at least one processor configured to execute instructions to:
- store additional data in an additional data area of memory-stored data of a memory including compressed data, the additional data including an error correcting code of the compressed data and compression information representing a degree of compression of the compressed data;
- and
- when reading out the memory-stored data from the memory, perform a readout process a number of times based on the degree of compression represented by the compression information in the additional data area, wherein
- the number of times that the readout process is performed is determined when reading out the memory-stored data from the memory on a basis of a data capacity before compression, a read capacity of one readout process, and the degree of compression represented by the compression information in the additional data area.
A non-transitory computer-readable medium storing thereon a program comprising instructions for causing a memory control device to:
- store additional data in an additional data area of memory-stored data of a memory including compressed data, the additional data including an error correcting code of the compressed data and compression information representing a degree of compression of the compressed data;
- and
- when reading out the memory-stored data from the memory, perform a readout process a number of times based on the degree of compression represented by the compression information in the additional data area, wherein
- the number of times that the readout process is performed is determined when reading out the memory-stored data from the memory on a basis of a data capacity before compression, a read capacity of one readout process, and the degree of compression represented by the compression information in the additional data area.
