    Abstract: A solution for detecting a multibyte error in a code word of a shortened error code is proposed, the shortened error code is a τ-byte-correcting error code, wherein bytes of the code word of the shortened error code determined a first range, the non-correctable multibyte error is detected if at least one of the following conditions is met: (a) at least one error position signal does not lie in the first range; (b) at least one error position signal indicates at least one error but fewer than terrors in the first range and no 1-byte error to (τ−1)-byte error is present.

    Abstract: Processing of a bit sequence is proposed, wherein (i) a first partial error syndrome s1 of an error syndrome and a second partial error syndrome s2 of the error syndrome are determined for the bit sequence, (ii) a first comparison value is determined on the basis of a bit position and the first partial error syndrome, (iii) a second comparison value is determined on the basis of the bit position and the second partial error syndrome, and (iv) the bit position is corrected should a comparison of the first comparison value with the second comparison value assume a specified value and otherwise the bit position is not corrected.

    Abstract: A solution is proposed for processing data bits, in which the data bits are transformed into first data bytes by means of a first transformation, in which the first data bytes are stored in a memory, in which second data bytes are read from the memory, in which each of the second data bytes, when there is no error, is a codeword of a block error code and in which one error signal per second data byte is determined that indicates whether or not this second data byte is a codeword.

    Abstract: A method is proposed for storing bits in memory cells of a memory, wherein in two successive write operations first and second wits are written to identical memory cells at an identical address, without the memory cells being erased after the first write operation, wherein first check bits are stored in further first memory cells and second check bits are stored in further second memory cells. A corresponding device is furthermore specified.

    Abstract: A circuitry for error correction includes a plurality of subcircuits for determining intermediate values Zw0, Zw1, Zw2, Zw3 to be used as coefficients in an error correction expression (z1i, z2i, . . . , zmi)=Zw3·α3ji+Zw2·α2ji+Zw1·αji+Zw0. The intermediate values Zw0, Zw1, Zw2, Zw3 are determined depending on subsyndromes s1, s3, s5 so that in case of a 1-bit, 2-bit, or 3-bit error zi=(z1i, z2i, . . . , zmi)=(0, 0, . . . , 0) when an error occurred in the bit position i, and zi=(z1i, z2i, . . . , zmi)≠(0, 0, . . . , 0) when no error occurred in the bit position i. A correction value Δvi= for the bit position i may then be determined on the basis of the error correction expression evaluated for αji.

    Abstract: Methods and apparatuses relating to error-tolerant memories are provided. In one example embodiment, output signals from at least three memory devices are supplied to an error correction device. The error correction device outputs a corrected data value in such a manner that, when the read data values match, this data value is output and, in at least one state in which the data values do not match, a previously output data value is retained.

    Abstract: An approach to correcting errors in a string of symbols is proposed, in which the string of symbols is transformed by a transformation τ into a first group of symbols and into a second group of symbols, and in which the group of symbols that has fewer erroneous symbols than the other group is corrected using a first error code.
