Abstract

PURPOSE:To eliminate the abnormal end in a disk cache control system, by reading the data on an error area of a cache control part out of a disk device and transferring this data to a read requester when an error is detected out of the data given to the read requester from the cache memory. CONSTITUTION:The data read out of a disk device 9 are held by a cache memory 2 and the caching operation given to the memory 2 is controlled by a cache control part 4. A memory check part 3 functions to detect the errors out of the data read out of the memory 2 and transferred to a CPU 11. When the part 3 actually detects an error, the part 4 reads the data on the relevant error area out of the device 9 and transfers it to the CPU 11. At the same time, the part 4 carries out a writing job again to the memory 2 to regenerate the memory check data.
