    摘要: At least one example embodiment discloses a method of compressing data in a storage device. The method includes determining a codeword length of a symbol using a first table indicating a relationship between a number of occurrences of the symbol in received data and the codeword length, determining a codeword having the codeword length for the symbol, and generating compressed data of the received data, the generating including converting the symbol into the codeword.
