Abstract
A data storage device includes a first memory device configured to store data having a first property, a second memory device configured to store data having a second property, and a controller. The controller selects data stored in the first memory device, and transfers the selected data to the second memory device or stores the selected data in another physical location of the first memory device selectively depending on an update count (UC) of an address at which the selected data is stored.
Claims23
A data storage device comprising:
- a first memory device configured to store data having a first property;
- a second memory device configured to store data having a second property;
- and
- a controller configured to select data stored at a certain physical location of the first memory device, and transfer the selected data to the second memory device or store the selected data at a different physical location of the first memory device selectively depending on an update count (UC) of an address at which the selected data is stored.
An operating method of a data storage device, the operating method comprising:
- selecting one or more data in a first memory device that stores data having a first property;
- and
- transferring the selected data to a second memory device that stores data having a second property, based on a result of comparing a UC corresponding to an address of the selected data with a threshold value.
A data storage device comprising:
- a request separator configured to classify a property of data requested from outside into a first property or a second property;
- a first memory device configured to store data having the first property;
- and
- a second memory device configured to store data having the second property.
