Storage device

A storage device comprising:

• a memory device that stores data;
• a storage controller that stores a data stream including a plurality of frame groups, in the memory device based on a write request from a host, each frame group including at least one frame;
• and
• a scaler that generates a mapping table in which, for each of the plurality of frame groups, at least one logical address assigned to the frame group is mapped to a frame group number assigned to the frame group,
• wherein, for each frame group of the plurality of frame groups included in the data stream, the scaler performs an operation of obtaining the at least one logical address for the frame group by referring to the mapping table and providing to the storage controller a batch read request to read all the at least one logical address assigned to the frame group, thereby to obtain each of the plurality of frame groups, encode the data stream using each of the plurality of frame groups, and provide a write request for the encoded data stream to the storage controller.

A storage device comprising:

• a memory device that stores data;
• a storage controller that controls the memory device;
• and
• a processor that obtains data stored in the memory device, performs a calculation on the data, and stores the data on which the calculation has been performed in the memory device,
• wherein the processor generates a mapping table in which at least one logical address assigned to the data is mapped to an identifier assigned to the data, and transmits to the storage controller a batch read request to read all the at least one logical address assigned to the data by referring to the mapping table, to obtain the data stored in the memory device.
