Data Storage Device and Data Maintenance Method Thereof

[0015]The following description is of the best-contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.

[0016]FIG. 1 is a schematic diagram illustrating an embodiment of an electronic system of an exemplary embodiment. The electronic system 100 includes a host 120 and a data storage device 140. The data storage device 140 includes a controller 160, a flash memory 180 and a temperature sensor 190. Furthermore, the data storage device 140 may operate in response to the commands received from the host 120. The controller 160 includes a computing unit 162, a non-volatile memory 164 (such as read only memory), a random access memory 165 and a timing device 166. The program code and data stored in the nonvolatile memory 164 may constitute firmware, and be performed by the computi
