Abstract: A data accessing method for a memory storage apparatus is provided. The method includes using a first check code circuit to generate a first check code corresponding to a first data stream and generating a first data set based on the first data stream and the first check code. The method also includes using a second check code circuit to obtain the first data stream and the first check code from the first data set and check the first data stream according to the first check code. The method still includes using a third check code circuit to generate a second check code according to the checked first data stream and generating a data frame based on the checked first data stream and the second check code and thereby programming the data frame into a physical programming unit.

Abstract: A data management method is provided. The method includes: dividing each of physical programming units into a data bits area and a spare bits area; generating first data management information corresponding to first data according to a first write command and the first data; determining whether the first data is compressible; and generating first data compression information corresponding to the first data. The method further includes: if the first data is compressible, compressing the first data to generate first compressed data, programming the first compressed data and the first data management information corresponding to the first data into a first data bits area of a first physical programming unit among the physical programming units, and programming the first data compression information into the first spare bits area of the first physical programming unit.
