Compensation of read errors

A method for compensating for a read error is disclosed, wherein each of n states are read from memory cells of a memory, the states being determined in a time domain. If the n states do not form a code word of a k-from-n code, a plurality of states from the n states, which were determined within a...

Zusammenfassung:A method for compensating for a read error is disclosed, wherein each of n states are read from memory cells of a memory, the states being determined in a time domain. If the n states do not form a code word of a k-from-n code, a plurality of states from the n states, which were determined within a reading window, are provided with a first valid assignment and fed to an error processing stage. If the error processing does not indicate an error, the n states are further processed with the first valid assignment, and if the error processing indicates an error, the plurality of states that were determined within the reading window are provided with a second valid assignment and the n states are further processed with the second valid assignment. Accordingly, a device, a system and a computer program product are also disclosed.
