<p>PROBLEM TO BE SOLVED: To avoid the loss of data held in a cache area due to power-off while suppressing the increase of a frequency in data write to the flash memory.SOLUTION: An information processor includes: a nonvolatile memory; a cache memory in which data to be written to the nonvolatile memory is stored; a power switch for stopping power supply to the information processor; a space change detection unit which detects the change in state of a space around the power switch; a notification unit for notifying a user of information; and a control unit which determines an operation of attempting to turn off the power switch, on the basis of a detection signal of the space change detection unit and, when recognizing the operation, causes the notification unit to notify the user that the operation of attempting to turn off the power switch is performed, and then writes data stored in the cache memory into the nonvolatile memory.</p> |
