Abstract
A controller includes a memory suitable for storing first data read from first memory blocks of a first super memory block included in a memory device; a rearranging unit suitable for rearranging the first data stored in the memory based on sequence-information of the first data stored in the memory; and a processor suitable for controlling the memory device to write the rearranged first data in a second super memory block of the memory device.
Claims20
A memory system comprising:
- a memory device including first and second groups including a plurality of memory blocks, respectively;
- and
- a controller configured to copy data stored in the first group into the second group,
- wherein the controller is configured to:
- sort the data read from the first group according to logical addresses;
- and
- program the sorted data into the second group.

A memory system comprising:
- a memory device including first and second groups including a plurality of memory blocks, respectively;
- and
- a controller configured to issue instructions to each of a plurality of processor cores,
- wherein each of the processor cores is configured to exclusively perform assigned operation in response to the respective instructions during a garbage collection operation, and
- wherein the controller includes:
- a first processor core configured to sort data read from the first group based on logical addresses;
- and
- a second processor core configured to program the sorted data into the second group.
5 more elements
A memory system comprising:
- a memory device including first and second groups including a plurality of memory blocks, respectively;
- and
- a controller configured to perform a garbage collection operation of copying data from the first group into the second group,
- wherein the controller is configured to:
- sort the data read from the first group if a size of the read data satisfies a predetermined condition;
- and
- program the sorted data into the second group.

A memory system comprising:
- a memory device including first and second groups including a plurality of memory blocks, respectively;
- and
- a controller configured to copy data from the first group into the second group during a garbage collection operation;
- wherein the controller is configured to:
- sort the data read from the first group if a characteristic of the read data satisfies a predetermined condition;
