Abstract: A method of storing survivor data generated while decoding channel polarization codes in a memory module includes setting a list size that corresponds to a number of decoder units used to decode the channel polarization codes, inputting a stream of input bits to the decoder units, and sequentially decoding the input bits. Each input bit is decoded using all previous input bits decoded before the each input bit. The method further includes selecting a plurality of survivor bits from among the decoded input bits, and storing the selected survivor bits in the memory module in a binary tree configuration. The number of edges in each level of the binary tree configuration does not exceed the list size.

Abstract: A method of operating a storage device including a nonvolatile memory can be provided by receiving, from a host, address change information including changing logical addresses for data to be stored in the nonvolatile memory. Physical addresses can be sequentially allocated to the changing logical addresses included in the address change information to provide a first journal. A portion of at least one physical address allocated to the changing logical addresses can be removed to provide a second journal and the second journal can be stored in the nonvolatile memory.

Abstract: A decoder unit is configured to perform a decoding on encoded data. The decoder unit includes a data bus comprising a number N of data lines, a local memory configured to store messages for a message-passing decoding and communicate the messages across the data bus, a plurality of first decoder processing units, wherein each first decoder processing unit is configured to perform the message-passing decoding by communicating with the local memory using a number A of the data channels, and a plurality of second decoder processing units, where each second decoder processing unit is configured to perform the message-passing decoding by communicating with the local memory using a number B of the data lines. N is at least two, A and B are less than or equal to N, and A is different from B.
