    摘要: A data processing system includes an error checking and correction (ECC) encoding circuit, an integrated circuit memory and a code rate control circuit. The ECC encoding circuit is configured to selectively apply a plurality of unique ECC code rates to write data received by the data processing system during an operation to convert the write data into encoded data, in response to a code rate selection signal. The integrated circuit memory includes a plurality of storage regions therein. These storage regions are configured to receive respective portions of the encoded data from the ECC encoding circuit. The code rate control circuit is configured to generate the code rate selection signal. This code rate selection signal has a value that specifies the corresponding ECC code rate to be applied to respective portions of the write data.

    摘要: A method may be provided to detect and correct data errors in a data system where a data message has been encoded with outer parity bits based on the data message using an outer encoding technique to provide an outer codeword and with inner parity bits based on the outer codeword using an inner encoding technique different than the outer encoding technique to provide an inner codeword. The method may include using the inner parity bits and an inner decoding technique corresponding to the inner encoding technique to perform inner decoding of the inner codeword. Responsive to performing inner decoding of the inner codeword without error, the data message may be extracted from a result of inner decoding the inner codeword without using the outer parity bits to decode the result of inner decoding the inner codeword. Related systems are also discussed.

    摘要: A nonvolatile memory device performs interleaving of data to be stored in each wordline (memory page), or of data to be stored in multiple wordlines (memory pages). The NVM includes a memory cell array, a storage circuit of a de-interleaving circuit, and a read/write circuit. The storage circuit of the de-interleaving circuit is configured to store program data to be written interleaved into the memory cell array. The read/write circuit is configured to control the interleaved/deinterleaved data input/output between the memory cell array and the storage circuit. The write operation unit size may be the same or different from the read operation unit size. The storage circuit stores the program data of integer k times of a common divisor of a read operation unit size and a write operation unit size of the read/write circuit, wherein k may equal ‘m’ (the number of bits stored in each memory cell of the NVM).

    摘要: A memory device includes a plurality of multi-bit memory cells. A plurality of input data bits are encoded according to an error correction code to generate a codeword including a plurality of groups of bits. Respective ones of the plurality of multi-bit memory cells are programmed to represent respective ones of the groups of bits of the codeword. The groups of bits of the codeword may be groups of consecutive bits. In some embodiments, the multi-bit memory cells are each configured to store in bits and a length of the codeword is an integer multiple of m. Data may be read from the multi-bit memory cells in page units or cell units to recover the codeword, and the recovered code word may be decode according to the error correction code to recover the input data bits.
