Übersetzung für "Fehlerkorrekturcode" in Englisch

Support error-correcting code (ECC) and/or buffered memory.

A simple and widely used error correction code is the Hamming code.

Function reads sectors from disk into memory Error Correcting Code (ECC)

It also includes an error correction code, so that the code can be read even if it becomes damaged.

An inconsistency may be a contradiction between a data content and an error correcting code of a page.

To ensure this property, the identifiers shall be preferably chosen from a MDS-Code matrix (maximum distance separable error correction code matrix).

When the data word is read from the memory, the parity bits stored with it are evaluated, as a result of which, depending on the number of parity bits, one or more bit errors can be detected and also corrected, depending on the error correction code used.

When a block is rewritten after an erase operation within the framework of the data exchange between blocks with different usage frequencies, the data are organized, by sector, as strings and stored with the respective generated ECC code—the redundant error correcting code—, and the modulo counter reading is noted there as well.

The CIRC check is an error correction code developed by Sony, CIRC representing the abbreviation of Cross Interleave Reed Solomon Code.

This can be accomplished simply by means of an error-correction code, so that after the data are corrected, one can continue to use the memory again.

However, if the ageing process is already so far along that the useful data can no longer be exactly reproduced by the error-correction code, then an error message signals this to the user, so that the memory can be replaced.

The data are thereby usually divided into blocks or data fields that can differ in length, and every block is supplemented during writing by protection characters corresponding to the selected error correction codes such as parity codes, CRC codes, and the like.

In the preferred embodiment example the error correction code is selected such that the secret vector CBV and the binary vector RBV (the biometric sample) have identical lengths.

At the same time, the auxiliary data is to not contain a reference to the key, so that an error correction code is complex to produce.

This method for operating a flash memory device according to the preferred embodiment of the invention makes use of an error correction code also in the erasing procedure.

Instead, an erasing procedure can be passed as accomplished, if at most a fixed number of single bit failures, five for example, or a variable number of single bit failures that is specified by the error correction code are verified in every erased group.

The error correction code may be applied in full or only partially to leave sufficient capacity for the ordinary programming operations.

It works principally in the same way in the erasing procedure as in the usual write and read operations, in which the error correction code is used to correct or reconstruct corrupted bits of the stored information.

If this is the case, the erasing procedure is regarded as completely accomplished, and the error correction code is applied to correct any deviation of the actual states of the erased memory cells from the state of erasure.

In the case A described above, this is an invalid page and/or a page with an inconsistency between its data content and its error correcting code.

The page determination means is preferably designed so that, in this case, it determines that page as being inconsistent whose contents contradict its error correcting code, irrespective of the fact whether the page carries the younger or the older time stamp.

An inconsistent page is, as mentioned above, a page with a contradiction between its content and its error correcting code or an older one of two pages having the same marking address.

In this case, it is also possible that two pages have the same association address, but that the content of one of the two pages contradicts the error correcting code of the page.
