Abstract
A data storage device includes at least one nonvolatile memory device; and a controller suitable for: generating parity data for data; performing a write operation for storing the data in at least one first memory region corresponding to at least one word line of the nonvolatile memory device; and selectively storing the parity data in at least one second memory region corresponding to the word line according to a size of the data, wherein the controller generates a plurality of parity data for the data according to respective types of the first memory region where the data are to be stored, and performs the write operation by storing parity data corresponding to respective types of the second memory region among the plurality of parity data, in the second memory region.
Claims20
A data storage device comprising:
- at least one nonvolatile memory device;
- and
- a controller suitable for:
- generating parity data for data;
- performing a write operation for storing the data in at least one first memory region corresponding to at least one word line of the nonvolatile memory device;
- and
- selectively storing the parity data in at least one second memory region corresponding to the word line according to a size of the data,
- wherein the controller generates a plurality of parity data for the data according to respective types of the first memory region where the data are to be stored, and performs the write operation by storing parity data corresponding to respective types of the second memory region among the plurality of parity data, in the second memory region.
A method for operating a data storage device, comprising:
- receiving data;
- and
- performing a write operation for storing the data in at least one first memory region corresponding to at least one word line of at least one nonvolatile memory device and selectively store parity data generated for the data, in at least one second memory region corresponding to the word line, according to a size of the data.
A method for operating a data storage device, comprising:
- generating parity data for data stored in a data buffer;
- and
- performing selectively a first write operation or a second write operation,
- wherein the first write operation is performed for storing data selected among the data, in at least one nonvolatile memory device, and
- wherein the second write operation is performed for storing the data and parity data selected among the parity data according to a size of the data, in the nonvolatile memory device.
