Abstract: A data storage device is provided. The data storage device a buffer configured to store a mapping table comprising physical block addresses (PBAs) corresponding to logical block addresses (LBAs), a non-volatile memory configured to store data; and a controller configured to control the buffer and the non-volatile. The controller is configured to read data stored at a first PBA of the non-volatile memory corresponding to a first LBA by referring to the mapping table when receiving a command to read data corresponding to the first LBA from outside of the data storage device, and, when a second LBA included in the data read from the non-volatile memory is different from the first LBA, retry reading, from the non-volatile memory, the data corresponding to the first LBA.

Abstract: A nonvolatile memory device includes a memory onto which a flash translation layer is loaded, a controller, and first and second memory areas. The controller is configured to execute the flash translation layer. The nonvolatile memory is configured to receive write requested data and corresponding category information. The flash translation layer is configured to map a logical address of the write requested data to a physical address, based on the category information, such that the write requested data is selectively stored in one of the first and second memory areas. The category information is based on a storage characteristic of the write requested data.
