Abstract: For enabling an efficient storage of received compressed data, an additional lossless compression is applied to the compressed data to obtain binary digits. The lossless compression is configured to result, on an average, in a higher percentage of binary digits having a first value than binary digits having a second value. The obtained binary digits are caused to be stored in a memory, wherein the storage of binary digits of the first value require less energy than or an equal amount of energy as the storage of binary digits of the second value.
