    摘要: Nonvolatile memory devices include support memory cell recovery during operations to erase blocks of nonvolatile (e.g., flash) memory cells. A nonvolatile memory system includes a flash memory device and a memory controller electrically coupled to the flash memory device. The memory controller is configured to control memory cell recovery operations within the flash memory device by issuing a first instruction(s) to the flash memory device that causes erased memory cells in the block of memory to become at least partially programmed memory cells and then issuing a second instruction(s) to the flash memory device that causes the at least partially programmed memory cells become fully erased.

    摘要: A code puncturing apparatus and method is provided. The apparatus includes: a codeword selection unit selecting continuous n−1-number of mother codewords from mother codewords generated from k-bit effective information, where k denotes a natural number, and one redundancy bit; and a puncturing unit selecting k-number of redundancy bits from redundancy bits included in the n−1-number of mother codewords, deleting remaining redundancy bits, and rearranging the n−1-number of mother codewords into an n·k bit-target codeword. Accordingly, a code rate of an Error Control Code (ECC) can be raised.
