Abstract
A storage device may include a memory storing data and a controller. Such a controller may receive a compression write command from an external device to compress and write original data, compress the original data, based on whether compression information that corresponds to the compression write command is supported, into compressed data using a preset value, and store the compressed data in the memory.
Claims21
A storage device comprising:
- a memory for storing data;
- and
- a controller configured to:
- receive a compression write command from an external device to compress and write original data;
- compress the original data, based on whether compression information that corresponds to the compression write command is supported, into compressed data using a preset value;
- and
- store the compressed data in the memory.
4 more elements
An operating method of a storage device comprising:
- receiving a compression write command from an external device to compress and write original data;
- determining whether a first compression algorithm and a first compression level that correspond to the compressed write command are supported;
- compressing, based on whether the first compression algorithm and the first compression level are supported, the original data into compressed data using the first compression algorithm or a preset reference compression algorithm;
- and
- storing the compressed data into a memory of the storage device.
2 more elements
A controller comprising:
- a memory interface configured to communicate with a memory storing data;
- and
- a control circuit configured to receive a compression write command from an external device to compress and write original data, to compress original data, based on whether a compression algorithm and a compression level that correspond to the compression write command are supported, into compressed data using the compression algorithm corresponding to the compression write command or a preset reference compression algorithm, and to store the compressed data in the memory.
