    摘要: A data compression method includes receiving an input data stream including a previous data block and a current data block, and executing a first comparison of a part of the previous data block with part of a previous reference data block, and a second comparison of the current data block with a current reference data block, where the first and second comparisons are executed in parallel. The method further includes selectively, based on results of the first and second comparisons, outputting the current data block or compressing an extended data block, where the extended data block includes the part of the previous data block and the current data block.

    摘要: A solid state drive (SSD) includes non-volatile memory devices and a RAID controller. Each of the non-volatile memory devices includes a memory cell array having a plurality of physical pages. The RAID controller performs a parity operation on 1st through (N−1)th physical page data to generate Nth physical page data, determines a physical page group including 1st through Nth physical pages that are selected from the 1st through Nth non-volatile memory devices, respectively, such that at least two of the 1st through Nth physical pages have different bit error rates from each other, and stores the 1st through Nth physical page data in the 1st through Nth physical pages, respectively.
