摘要： Flash memory devices and associated methods are described for controlling data errors in the devices through various forms of decoding, error correction, and wear concentration. To this end, a flash memory device may be partitioned into a plurality of sectors. Data may then be received from, for example, a host processor for storage within the flash memory device. Storage durations of the data are then estimated and the data is stored in the data sectors based on those estimated storage durations.

摘要： In a method of detecting an error pattern in a codeword transmitted across a noisy communication channel, a codeword is detected. A syndrome is then generated by applying a generator polynomial to the codeword. The generator polynomial is adapted to produce a distinct syndrome set for each of “L” (L>1) different error patterns potentially introduced in the codeword during transmission across the communication channel. A type of an error pattern within the codeword is detected based on the syndrome or a shifted version of the syndrome, and then a start position of the error pattern within the codeword.

摘要： Techniques are described for detecting error events in codewords detected from data signals transmitted via a communication system. The error events are detected with an error detection code that corresponds to one or more dominant error events for the communication system. The invention develops a class of error detection codes to detect specific error events of known types. In some embodiments, the communication system comprises a recording system. The error detection coding method may be used in conjunction with error correction processing to provide substantial performance gain compared to conventional parity-based post processing methods. For example, the error correction processing may include one or more correlation filters that correspond to the one or more dominant error events for the communication system. A correction module may correct the codeword based on a type of the detected error event and a location of the detected error event in the codeword.
