    摘要: A method and system for making error corrections on digital information coded as symbol sequences, for example digital information stored in electronic memory systems or transmitted from and to these systems is described, provides the transmission of sequences incorporating a portion of error corrector code allowing the sequence which is more probably the original transmitted through the calculation of an error syndrome using a parity matrix to be restored when received. Advantageously according to embodiments of the invention, the error code incorporated in the original sequence belongs to a non Boolean group.

    摘要: A first codeword may be constructed from a cache tag in a cache and an error correction code corresponding to the cache tag. A second codeword may be constructed from a search tag and an error correction code corresponding to the search tag. A hamming distance may be calculated between the first codeword and the second codeword. If the hamming distance is less than or equal to a threshold, a cache hit may be signaled. If the hamming distance is above the threshold, a cache miss may be signaled.

    摘要: A method is described that includes reading a cache tag and the cache tag's corresponding ECC from storage circuitry of a cache. The method also includes generating an ECC for a search tag. The method also includes calculating a hamming distance between a) the cache tag and its corresponding ECC and b) the search tag and its corresponding ECC. The method also includes determining if the cache tag matches the search tag by comparing the hamming distance against a threshold.

    摘要: A channel has a first and a second end. The first end of the channel is coupled to a transmitter. The channel is capable of transmitting symbols selected from a symbol set from the first end to the second end. The channel exhibits incomplete error introduction properties. A code comprises a set of code words. The elements of the set of code words are one or more code symbols long. The code symbols are members of the symbol set. The minimum modified Hamming separation between the elements of the set of code words in light of the error introduction properties of the channel is greater than the minimum Hamming distance between the elements of the set of code words. A memory device, a method of using the channel, and a method of generating the code are also described.

    摘要: A method of encoding data for transmission from a source to a destination over a communications channel is provided. A plurality of redundant symbols are generated from an ordered set of input symbols to be transmitted. A plurality of output symbols are generated from a combined set of symbols including the input symbols and the redundant symbols, wherein the number of possible output symbols is much larger than the number of symbols in the combined set of symbols, wherein at least one output symbol is generated from more than one symbol in the combined set of symbols and from less than all of the symbols in the combined set of symbols, and such that the ordered set of input symbols can be regenerated to a desired degree of accuracy from any predetermined number, N, of the output symbols.

    摘要: In a method of reading data from a non-volatile memory device, read data is generated based on a word line voltage. The read data includes data read from a plurality of sectors included in the non-volatile memory device. Bad sector data is transferred data based on read data and bad sector information. The bad sector data corresponds to data read from at least one bad sector included in the plurality of sectors. The bad sector information is updated by checking error bits of the bad sector data. The word line voltage is generated based on the updated bad sector information.
