  • Patent number: 11799497
    Abstract: A method for operating a storage controller includes receiving a first read command, performing a first read of data stored in a nonvolatile memory using a first read level and receiving a first read data, performing first error correction decoding of the first read data to determine whether the first error correction decoding succeeds, determining a second read level using a predetermined method, and determining a first soft decision offset value of the second read level, reading data stored in the nonvolatile memory using the determined second read level and the first soft decision offset value and receiving a first soft decision data, performing second error correction decoding of the first soft decision data to determine whether the second error correction decoding succeeds, and storing the second read level, a first method used to determine the second read level and the first soft decision offset value.

  • Patent number: 6462592
    Abstract: The present invention relates to a clock signal converting apparatus of a transmission system which is capable of coinciding synchronization of clock signals of a system by sharing signals of a first clock signal generator as a working unit and a second clock signal generator as a protection unit in common. In addition, the second clock signal generator can output system signals having same phase with the first clock signal generator by using output of the first clock signal as a reset signal of the counter of the second clock signal generator.
