US 11,079,952 B2 · Data storage device performing scan operations on memory regions to move data and operation method thereof

Abstract

A data storage device may include a storage including a plurality of memory blocks each composed of a plurality of pages and divided into a first region including some of the plurality of memory blocks and a second region including remaining memory blocks of the plurality of memory blocks; and a controller configured to control data input and output of the storage in response to a request of a host, determine whether to move data stored in a memory block of the first region by performing a first scan operation on the memory block of the first region, and determine whether to move data stored in at least one memory block of the second region by performing a second scan operation on the at least one memory block of the second region after the first scan operation is completed.

Dependent claims

A data storage device comprising:

a storage including a plurality of memory blocks each composed of a plurality of pages and divided into a first region including some of the plurality of memory blocks and a second region including remaining memory blocks of the plurality of memory blocks;
and
a controller configured to:
control data input and output of the storage in response to a request of a host,
determine whether to move data stored in a memory block of the first region by performing a first scan operation on the memory block of the first region, and
determine whether to move data stored in at least one memory block of the second region by performing a second scan operation on the at least one memory block of the second region after the first scan operation is completed,
wherein the controller is configured to preferentially scan the first region than the second region.

An operation method of a data storage device including a storage including a plurality of memory blocks each composed of a plurality of pages and divided into a first region including some of the plurality of memory blocks and a second region including remaining memory blocks and a controller configured to control data input/output of the storage in response to a request of a host, the operation method comprising:

scanning, in a first scan operation, by the controller, a memory block of the first region;
determining, in a first determination operation, by the controller, whether to move data stored in the memory block of the first region based on a result of the first scan operation;
scanning, in a second scan operation, by the controller, at least one memory block of the second region;
and
determining, in a second determination operation, by the controller, whether to move data stored in the memory block of the second region based on a result of the second scan operation,
wherein the controller is configured to preferentially scan the first region than the second region.
