Abstract
An inverted page table including mapping information between a physical address of a first memory, included in a data storage device and used for processing data of a host device, and a logical address of at least a partial storage area of a second memory having a size larger than the first memory is disclosed. A storage virtual memory may be provided to the host device, and by expanding the size of a physical memory recognized by the host device, the performance of data processing of the host device may be improved.
Claims20
A data storage device comprising:
- a first memory;
- a second memory;
- and
- a controller configured to provide a storage virtual memory of a size corresponding to at least a partial storage area of the second memory, and configured to process a page request from a host device for the first memory using an inverted page table, which includes mapping information between a logical address from the storage virtual memory and a physical address of the first memory.

A data storage device comprising:
- a first memory;
- and
- a controller configured to provide a storage virtual memory of a size corresponding to at least a partial storage area of a second memory, which is distinguished from the first memory, and to process a page request from a host device by using an inverted page table, which includes mapping information between a logical address according to the storage virtual memory and a physical address of the first memory.
A computing system comprising:
- a data storage device including a first memory;
- and
- a host device configured to perform data processing using the data storage device,
- wherein the host device recognizes a storage virtual memory of a size corresponding to at least a partial storage area of a second memory, which is distinguished from the first memory, as a physical memory, and performs data processing by using an inverted page table that includes mapping information between a logical address according to the storage virtual memory and a physical address of the first memory.
