摘要： Methods include receiving data and an ECC code read from a memory array, generating an ECC code from the received data, and determining whether the received data is corrupted by evaluating the generated ECC code against the ECC code read from the memory array. If the received data is determined to be corrupted, a correction algorithm and a recorded likely state of a known bad/questionable bit of the received data may be used to correct error in the received data. Alternatively, if the received data is determined to be corrupted, the correction algorithm and a recorded location of a known bad/questionable bit of the received data may be used to correct error in the received data.

摘要： Improved memory devices, circuitry, and data methods are described that facilitate the detection and correction of data in memory systems or devices in combination with a stored record of known flaws, errors, or questionable data bits of a read memory row or block to allow for more efficient processing and correction of these errors. An embodiment of the present invention utilizes an erasure pointer that can store the location of N bad or questionable bits in the memory segment that is currently being read, where for each bit stored by the erasure pointer the embodiment also contains 2N ECC generators to allow the read data to be quickly checked with the known bad bits in each possible state. This allows the read data to then be easily corrected on the fly before it is transferred by selecting the bad bit state indicated by the ECC generator detecting an uncorrupted read.

摘要： Data is read from a memory array. Before being stored in a data buffer, a Hamming code detection operation and a Reed-Solomon code detection operation are operated in parallel to determine if the data word has any errors. The results of the parallel detection operations are communicated to a controller circuit. If an error is present that can be corrected by the Hamming code correction operation, this is performed and the Reed-Solomon code detection operation is performed on the corrected word. If the error is uncorrectable by the Hamming code, the Reed-Solomon code correction operation is performed on the word.

摘要： Methods of data handling include receiving data having a previously-generated error correction code and generating one or more error correction codes for the data, with each error correction code corresponding to the data having one or more particular bits of the data in differing data states. Such methods further include comparing the generated one or more error correction codes to the previously-generated error correction code, and if a particular one of the generated one or more error correction codes matches the previously-generated error correction code, transmitting the data having its one or more particular bits in the data states corresponding to that particular one of the generated one or more error correction codes. Methods of data handling may further include prioritizing the error correction in response to at least locations of known bad or questionable bits of the data.

摘要： Improved memory devices, circuitry, and data methods are described that facilitate the detection and correction of data in memory systems or devices by encoding the data bits of a memory row or block in a non-systematic ECC code. This allows memory embodiments of the present invention to utilize reduced complexity error detection and correction hardware and/or routines to efficiently detect and correct corrupted user data in a segment of memory, such as a sector, word line row, or erase block. Additionally, in embodiments of the present invention user data is not stored in a plaintext format in the memory array, allowing for an increased level of data security. Further, in embodiments of the present invention, the ECC code is distributed throughout the stored data in the memory segment, increasing the robustness of the ECC code and its resistance to damage or data corruption.
