More Information
Summary:A memory system may include a first memory having a first operating speed, and a second memory having a second operating speed which is different from the first operating speed. A compression device may compress data of the first memory, and may transfer the compressed data to the second memory. The compression device may select a compression scheme among a plurality of compression schemes based on at least one characteristic of the data of the first memory and a data processing combination selected among a plurality of data processing combinations between a series of data processing units of the first memory and a series of data processing units of the second memory, and may compress the data of the first memory according to the selected compression scheme.
