ABSTRACT:
First blocks with data units are encoded or decoded in a first error protection code in an encoding or decoding device. A sub-set of data units, comprising one data unit from each first block, is encoded or decoded in a second block of the second error protection code. The data units of each first block are stored so as to be group-wise distributed among different pages of a paged memory. On each page data units from different first blocks are stored, so that upon reading of the data units of the sub-set the data units can also be written again so as to be group-wise distributed among different pages. The number of necessary page address changes is thus minimized.
