Abstract
A data storage device may include: a memory device; and a controller configured to control an operation of the memory device. The controller may include a first CPU and a second CPU including a plurality of cores, wherein the first CPU compares P/E (Program/Erase) average counts for the plurality of cores of the second CPU, and performs a remapping operation of changing a core which is mapped to logical block addresses received from a host.
Claims16
A data storage device comprising:
- a memory device;
- and
- a controller configured to control an operation of the memory device,
- wherein the controller comprises a first central processing unit (CPU) and a second CPU including a plurality of cores,
- wherein the first CPU compares P/E (Program/Erase) average counts for the plurality of cores of the second CPU, and performs a remapping operation of changing a core which is mapped to logical block addresses received from a host, when there is a first core and a second core, among the plurality of cores, that each have a P/E average count and a difference of the P/E average counts for the first core and the second core is equal to or more than a preset threshold value.

An operating method of a data storage device which includes a memory device;
- and a controller configured to control an operation of the memory device and having a first central processing unit (CPU) and a second CPU including a plurality of cores, the operating method comprising:
- comparing Program/Erase (P/E) average counts for the plurality of cores of the second CPU;
- checking whether there is a first core and a second core, among the plurality of cores of the second CPU, that each have a P/E average count and a difference of the P/E average counts for the first core and the second core is equal to or more than a preset threshold value;
- and
- performing a remapping operation of changing a core which is mapped to logical block addresses received from a host, when there are the first core and the second core.
