Abstract
During TRIM processing, an apparatus cannot read/write data from/to a semiconductor storage device, and thus cannot perform processing using the device. If the TRIM processing is executed irrespective of a user's intention, the user is to wait for completion of the TRIM processing before performing a desired function of the apparatus. The apparatus includes a nonvolatile storage unit having semiconductor areas, a control unit configured to count a value of at least one type of data, an execution unit configured to execute TRIM processing that notifies the storage unit of an unused area among the semiconductor areas and performs wear leveling on an area in use among the semiconductor areas, and a notification unit configured to provide a notification prompting the execution of the TRIM processing when the counted value of the data satisfies a condition for a threshold.
