Abstract
Provided is an apparatus and method for managing mapping information of a nonvolatile memory, in which a time period required for a request for access to a logic sector of the nonvolatile memory is minimized. The apparatus includes an extractor which extracts a logical sector mapped with each physical sector in physical units mapped with a predetermined logical unit, a mapping information generator which generates mapping information of logical sectors belonging to the logical unit including the extracted logical sector, and a mapping information memory which stores the generated mapping information.
Claims16
An apparatus for managing mapping information of a nonvolatile memory, the apparatus comprising:
- an extractor which extracts a logical sector mapped with each of a plurality of physical sectors in a plurality of physical units mapped with a logical unit;
- a mapping information generator which generates mapping information of a plurality of logical sectors belonging to the logical unit, wherein said plurality of logical sectors includes the extracted logical sector;
- and
- a mapping information memory which stores the generated mapping information.
A method of managing mapping information of a nonvolatile memory, the method comprising:
- extracting a logical sector mapped with each of a plurality of physical sectors in a plurality of physical units mapped with a logical unit;
- generating mapping information of a plurality of logical sectors belonging to the logical unit, wherein said plurality of logical sectors includes the extracted logical sector;
- and
- storing the generated mapping information.
