INFORMATION PROCESSING APPARATUS, AND CONTROL METHOD THEREOF
First Claim
1. An information processing apparatus comprising:
- a first storage unit that has a power restricted state in which supply of power is restricted and an activated state in which power is supplied;
a second storage unit that has a higher access speed than the first storage unit;
a determination unit configured to determine whether or not the first storage unit needs to be used based on a remaining storage capacity in which data can be stored in the second storage unit; and
a control unit configured to cause, in a state in which data can be stored in the second storage unit, the first storage unit to be in the power restricted state, and to make the first storage unit switch from the power restricted state to the activated state in a case where the determination unit determines, while the first storage unit is in the power restricted state, that the first storage unit needs to be used.

Abstract
An information processing apparatus includes a first storage unit that has a power restricted state and an activated state, and a second storage that has a higher access speed than the first storage. A determination unit determines whether or not the first storage unit needs to be used based on a remaining storage capacity in which data can be stored in the second storage unit. A control unit causes, in a state where data can be stored in the second storage unit, the first storage unit to be in the power restricted state, and makes the first storage unit switch from the power restricted state to the activated state in a case where it is determined, while the first storage unit is in the power restricted state, that the first storage unit needs to be used.

14. An information processing apparatus comprising:
-
a first storage unit that has a power restricted state in which supply of power is restricted and an activated state in which the power is supplied; a second storage unit that has a higher access speed than the first storage unit; and a control unit configured to cause, in a state in which data can be stored in the second storage unit, the first storage unit to be in the power restricted state, and to make the first storage unit switch from the power restricted state to the activated state in accordance with a remaining storage capacity of the second storage unit becoming less than a predetermined capacity while the first storage unit is in the power restricted state, wherein the control unit controls write processing so as to write data in the second storage unit when the first storage unit is in the power restricted state, and to write data in the first storage unit after the first storage unit is switched to the activated state.

15. A control method of an information processing apparatus that comprises:
- a first storage unit that has a power restricted state in which supply of power is restricted and an activated state in which power is supplied; and
a second storage unit that has a higher access speed than the first storage unit, the method comprising;determining whether or not the first storage unit needs to be used based on a remaining storage capacity in which data can be stored in the second storage unit; and causing, in a state in which data can be stored in the second storage unit, the first storage unit to be in the power restricted state, and of making the first storage unit switch from the power restricted state to the activated state in a case where it is determined in the determining, while the first storage unit is in the power restricted state, that the first storage unit needs to be used.
- a first storage unit that has a power restricted state in which supply of power is restricted and an activated state in which power is supplied; and
