Abstract
A storage device processes storage-free stuck bits information when writing and reading stored on the memory device. A controller encodes the data with cyclic error-correcting codes to generate a codeword and determines that a location in the memory device where codeword is be stored includes a stuck bit. Rather than storing the stuck bits information, when storing the codeword, the controller generates an encoding mask, adds the encoding mask to the codeword to generate encoded data, and stores the encoded data on the memory device. When reading the encoded data, the controller generates a list of decoding masks including the encoding mask, goes through the lists and adds a decoding mask to the encoded data. The controller decodes the encoded data with the encoding mask from the list and returns the data.
