Abstract:
Disclosed is a nonvolatile cache memory including a nonvolatile memory part and a cache controller. The nonvolatile memory part is configured to store cache data. The cache controller is configured to control reading and writing of the cache data with respect to the nonvolatile memory part. Further, the cache controller is configured to perform, as a preparation for an interruption of power supply, standby preparation processing to generate standby state data and store the generated standby state data in the nonvolatile memory part. Further, the cache controller is configured to perform, at resumption of the power supply, restoration processing of the cache data stored in the nonvolatile memory part using the standby state data.
