Abstract

An apparatus includes a processing unit and a memory. The processing unit is configured to encode a plurality of bits to obtain a plurality of encoded bits, the processing unit is configured to determine an inversion decision. When the inversion decision indicates that the subset of the encoded bits shall not be inverted, the processing unit is configured to store, as a stored word, bits of the first codeword into the memory. When the inversion decision indicates that the subset of the encoded bits shall be inverted, the processing unit is configured to invert each encoded bit of a subset of the encoded bits to obtain a second codeword and to store the second codeword into the memory.
