Abstract
A memory system includes: a memory device suitable for storing target map data; and a controller suitable for controlling the memory device, wherein the controller includes: an address management component suitable for establishing a plurality of indexes, one index for each of a plurality of map data; and a processor suitable for: reading the target map data from the memory device; and storing the target map data into a target map block of the memory device, wherein the target map block is determined according to the indexes.
Claims19
A memory system comprising:
- a memory device suitable for storing target map data;
- and
- a controller suitable for controlling the memory device,
- wherein the controller includes:
- an address management component suitable for establishing a plurality of indexes, one index for each of a plurality of map data;
- and
- a processor suitable for:
- reading the target map data from the memory device;
- and
- storing the target map data into a target map block of the memory device, wherein the target map block is determined according to the indexes.
An operating method of a memory system, the method comprising:
- establishing, using a controller, a plurality of indexes, one index for each of a plurality of map data;
- controlling a memory device to read stored target map data from the memory device;
- and
- controlling the memory device to store the target map data into a target map block, which is determined according to the indexes, of the memory device.
A memory system comprising:
- a memory device suitable for storing a plurality of map data and a location table identifying locations of the plurality of map data;
- and
- a controller suitable for generating indexes, each index corresponding to a respective one of the plurality of map data, and loading and updating at least one of the plurality of map data based on the indexes,
- wherein the controller is configured to use the indexes for sorting the plurality of map data and updating the location table, and to check the indexes for generating a new index for a map data having no corresponding index.
