    摘要: Provided are apparatuses for decoding a concatenated code and methods for the same that may improve the decoding speed of a concatenated code based on a likelihood value with respect to output from a plurality of decoders.A method of decoding a concatenated code may include: calculating a likelihood value of concatenated encoded received data; performing first decoding for the received data based on the calculated likelihood value to generate first decoded data; performing second decoding for the first decoded data to generate second decoded data; and determining whether to perform iterative decoding based on the second decoded data.According to example embodiments, it is possible to directly manage the quality of concatenated decoded data to thereby accurately determine whether to perform iterative decoding for concatenated encoded data. Also, it may be possible to quickly decode concatenated encoded received data.

    摘要: Memory devices and/or methods of managing memory data errors are provided. A memory device detects and corrects an error bit of data read from a plurality of memory cells, and identifies a memory cell storing the detected error bit. The memory device assigns a verification voltage to each of the plurality of first memory cells, the assigned verification voltage corresponding to the corrected bit for the identified memory cell, the assigned verification voltage corresponding to the read data for the remaining memory cells. The memory device readjusts the data stored in the plurality of memory cells using the assigned verification voltage. Through this, it is possible to increase a retention period of the data of the memory device.
