Zusammenfassung:	Lossless data compression and depression devices and lossless data compression and decompression methods are provided. The lossless data compression device includes a processor and an entropy coding circuit. The processor is arranged to determine whether a raw data stream matches data items in a dictionary when a compression command for the raw data stream is received and output corresponding codewords according to the determination result. The entropy coding circuit is arranged to perform entropy coding on the corresponding codewords to obtain a compressed data stream.
