Abstract
In order to reduce the degradation deviation of each area of a volatile memory storing data related to the non-volatile memory included in a storage device, an area storing the corresponding data may be changed and set according to the type of data stored in the volatile memory at a preset time.
Claims17
A storage device comprising:
- a non-volatile memory;
- a volatile memory including a plurality of areas in which a plurality of types of information associated with the non-volatile memory are stored;
- and
- a controller configured to select at least one area of the plurality of areas based on a type of information stored in each of the plurality of areas, and to change and allocate at least a portion of the selected area at a specific time.
1 more element
An operating method of a storage device comprising:
- checking an existing area allocated as an area for storing a first type of information associated with an externally located memory upon booting;
- allocating a first use area for storing the first type of information by changing at least a portion of the existing area;
- and
- allocating at least a portion of an area other than the first use area as a second use area for storing a second type of information associated with the externally located memory.
1 more element
A controller comprising:
- a first processing module configured to process data stored in a first memory;
- and
- a second processing module configured to perform processing relating to data stored in a second memory storing information associated with the first memory, and to change and allocate an area storing map data related to data stored in the first memory, from among a plurality of areas included in the second memory, at every booting.
