Data storage device

Abstract

A data storage device includes a nonvolatile memory device; and a controller suitable for controlling an operation of the nonvolatile memory device based on a request from a host device, wherein the controller includes a first core activated in a normal mode and a second core activated in a standby mode.

What is claimed is: 
     
         1 . A data storage device comprising:
 a nonvolatile memory device; and   a controller suitable for controlling an operation of the nonvolatile memory device based on a request from a host,   wherein the controller includes a first core and a second core each of which is activated or deactivated in different modes,   wherein the first core performs both host-dependent jobs and host-independent jobs, and   wherein the second core performs only host-independent jobs.   
     
     
         2 . The data storage device according to  claim 1 , wherein the first core is activated in a normal mode and deactivated in a standby mode. 
     
     
         3 . The data storage device according to  claim 2 , wherein the second core is activated in the standby mode and deactivated in the normal mode. 
     
     
         4 . The data storage device according to  claim 2 , wherein the data storage device operates in the normal mode when there is a job requested from host, and operates in the standby mode when there is no job requested from the host. 
     
     
         5 . The data storage device according to  claim 1 , wherein the host-dependent job includes a job for providing data read from the nonvolatile memory device to the host, or a job for storing data provided from the host in the nonvolatile memory device. 
     
     
         6 . The data storage device according to  claim 1 , wherein the host-independent job includes a job for managing the nonvolatile memory device.
