Abstract
A data storage device includes a nonvolatile memory device including a plurality of planes each of which includes a plurality of memory units; and a controller configured to determine a plane distribution of one or more first planes which include one or more first memory units, determine whether the plane distribution satisfies a predetermined condition, select a memory unit in each of one or more second planes, as a second memory unit, depending on the determination result of the satisfaction of the predetermined condition, and perform a read-access in the first memory units and the second memory units simultaneously.
Claims20
A data storage device comprising:
- a nonvolatile memory device including a plurality of planes each of which includes a plurality of memory units;
- and
- a controller configured to determine a plane distribution of one or more first planes which include one or more first memory units, determine whether the plane distribution satisfies a predetermined condition, select a memory unit in each of one or more second planes as a second memory unit depending on the determination result of the satisfaction of the predetermined condition, and perform a read-access in the first memory units and the second memory units simultaneously.
A method for operating a data storage device including a nonvolatile memory device including a plurality of planes each of which includes a plurality of memory units, the method comprising:
- determining a plane distribution of one or more first planes which include one or more first memory units;
- determining whether the plane distribution satisfies a predetermined condition;
- selecting a memory unit in each of one or more second planes as a second memory unit depending on the determination result of the satisfaction of the predetermined condition;
- and
- performing read-access in the first memory units and the second memory units simultaneously.
A data storage device comprising:
- a nonvolatile memory device including a plurality of planes, and configured to support a multi-plane read operation for the plurality of planes;
- and
- a controller configured to process the multi-plane read operation by merging a host read operation and a background read operation,
- wherein host target memory units of the host read operation and background target memory units of the background read operation have different offset values.
