Abstract
According to an embodiment of the present disclosure, an electronic device may comprise a memory and a processor configured to produce compressed data by compressing data including a first block and a second block stored in the memory, wherein the processor may be configured to include a first replacement data table corresponding to first sub-data in the compressed data, the first sub-data included in the first block, and the first replacement data table produced based on, at least, rankings of first frequencies for the first sub-data, and include information for reference to the first replacement data table, corresponding to the second block, when second sub-data included in the second block and rankings of second frequencies for the second sub-data meet a designated condition with respect to the first sub-data included in the first block and the rankings of the first frequencies. Other embodiments are also possible.
