    Abstract: Provided are data compression method, data compression apparatus, and memory system. The data compression method includes receiving input data and generating a hash key for the input data, searching a hash table with the generated hash key, and if it is determined that the input data is a hash hit, compressing the input data using the hash table; and searching a cache memory with the input data, and if it is determined that the input data is a cache hit, compressing the input data using the cache memory.

    Abstract translation: 提供数据压缩方法,数据压缩装置和存储系统。 数据压缩方法包括:接收输入数据并产生用于输入数据的哈希密钥,用生成的散列密钥搜索散列表,以及如果确定输入数据是散列命中,则使用散列表压缩输入数据 ; 以及使用所述输入数据搜索高速缓冲存储器,并且如果确定所述输入数据是高速缓存命中,则使用所述高速缓冲存储器压缩所述输入数据。

    Abstract: A hard-decision decoding method includes performing operations necessary for first updating of a check node while loading data, which is input to a decoder, to an input buffer; first updating the check node by using a result of the performing of the operations after storing data, corresponding to one codeword, to the input buffer; and performing low-density parity check (LDPC) decoding by using a result of the first updating of the check node.

    Abstract translation: 硬判决解码方法包括:将输入到解码器的数据加载到输入缓冲器,执行第一更新校验节点所必需的操作; 首先通过使用存储对应于一个码字的数据之后的操作的结果更新所述校验节点到所述输入缓冲器; 以及通过使用校验节点的第一次更新的结果来执行低密度奇偶校验(LDPC)解码。
