Abstract
A descrambling method is suitable for improving the data transfer rate and fast data processing separate scrambled data into a plurality of data groups each including plural pieces of scrambled unit data. Initial scramble patterns are respectively assigned to the data groups. An initial scramble pattern is prepared and assigned to a specific data group. A first scramble pattern is generated in one clock cycle using the prepared initial scramble pattern and then one of the scrambled unit data pieces in the specific data group is prepared. A descrambling operation using the first scramble pattern and the prepared one scrambled unit data piece is then performed to produce an original data piece.
