  • Patent number: 8769188
    Abstract: The invention provides a nonvolatile memory controller. In one embodiment, the nonvolatile memory controller receives new data for writing a nonvolatile memory from a host, and comprises a signature calculating circuit, a signature buffer, a signature comparison circuit, a data comparison circuit, and a nonvolatile memory interface circuit. The signature calculating circuit calculates a first signature according to the new data. The signature buffer outputs a second signature corresponding to old data stored in the nonvolatile memory, wherein the old data has the same logical address as that of the new data. The signature comparison circuit determines whether the first signature is identical to the second signature. The nonvolatile memory interface circuit writes the new data to the nonvolatile memory when the first signature is determined to be different from the second signature by the signature comparison circuit.

  • Patent number: 8559280
    Abstract: The invention provides a method for data recording of an optical disk drive. First, raw data is encoded to obtain a plurality of recording units of encoded data to be stored in a memory. The encoded data stored in the memory is then recorded to an optical disk. A predetermined number of recording units of the encoded data is then reserved in the memory as reserved data without being recorded onto the optical disk. The recorded data read from the optical disk is then compared to the corresponding encoded data stored in the memory to verify correctness of the recorded data. The reserved data is then recorded to the optical disk after correctness verification of the recorded data is completed. Finally, the aforementioned steps are repeated until there is no more raw data left as a source for encoding.
