摘要 |
<p>The present invention aims to restore the data saved in a nonvolatile memory to a cache memory, even if there is not a read response from the nonvolatile memory. In a data saving operation, parity data of to-be-saved data is generated, and the to-be-saved data and the parity data having CRCs and AIDs added thereto are written into a flash memory (141 or 142). In a data restoring operation, if an operation to read data from the flash memory (141 or 142) is not completed within a predetermined period of time, the data reading operation is suspended, and additional data is set. The to-be-saved data having a data error corrected with the parity data is then written into the cache memory (130).</p> |
