Abstract
A storage device is provided which includes a nonvolatile memory device and a controller configured to write meta information, indicating that a transfer of unit data is completed, in a buffer memory when the unit data is transferred to the buffer memory from the nonvolatile memory device.
Claims19
A storage device comprising:
- a nonvolatile memory device configured to store data having a plurality of unit data;
- and
- a controller configured to request the nonvolatile memory device to transfer the data having the plurality of unit data and to write meta information, indicating that a transfer of a unit data among the plurality of unit data from the nonvolatile memory device to a buffer memory is completed, in a meta area of the buffer memory when the unit data among the plurality of unit data is transferred to the buffer memory from the nonvolatile memory device.
A storage device comprising:
- a nonvolatile memory device configured to store data having a plurality of unit data;
- a buffer memory configured to temporarily store data transferred from the nonvolatile memory device;
- and
- a nonvolatile memory direct memory access (DMA) configured to be in charge of data exchange between the nonvolatile memory device and the buffer memory, to request the nonvolatile memory to transfer the data having the plurality of unit data and when a unit data among the plurality of unit data sent from the nonvolatile memory device is stored in the buffer memory, to write transfer completion information, indicating that the unit data among the plurality of unit data is stored in the buffer memory, in a meta area of the buffer memory.

A storage device comprising:
- a nonvolatile memory device configured to store data having a plurality of unit data;
- and
- a controller comprising a buffer memory and a meta area and configured to request the nonvolatile memory device to transfer the data having the plurality of unit data, the buffer memory configured to temporarily store unit data from the nonvolatile memory device and the meta area configured to store meta information corresponding to the unit data,
- wherein when a transfer of the unit data among the plurality of unit data from the nonvolatile memory to the buffer memory is completed, the controller writes the meta information that indicates that a transfer of the unit data among the plurality of unit data from the nonvolatile memory to the buffer memory is completed.
