Verifying the validity of data saved at power down by comparing the time of save to time of power-off upon start up
Abstract:
An information processing apparatus including: a nonvolatile memory; a volatile system memory in which predetermined data stored in the nonvolatile memory is developed; a control section to save the predetermined data stored in the system memory in the nonvolatile memory when a start of power-off operation is detected; and a storage section that stores a first timing information representing a time point of terminating the operation of saving the predetermined data in the nonvolatile memory, and a second timing information representing a power-off time point, wherein the control section compares the first timing information stored in the storage section with the second timing information, subsequent to the next operation of turning on of the power.
