    Abstract: A method of operating a memory device includes applying an initial read voltage to a selected wordline to perform a read operation on memory cells connected to the selected wordline, determining whether a read failure occurs with respect to one or more of the memory cells, upon determining that a read failure has occurred with respect to some of the memory cells, determining threshold voltage distribution information for distinct groups of the memory cells, and determining a new read voltage to be applied to the selected wordline based on the threshold voltage distribution information.

    Abstract: A non-volatile memory device includes a memory cell array including a plurality of memory cells, a page buffer circuit, and a control logic circuit. The page buffer circuit includes a plurality of first page buffers and a plurality of second page buffers, each including a sense latch, a data latch, and a cache latch. The sense latch senses data stored in the memory cell array and dumps the sensed data to the data latch, the data latch dumps the data dumped by the sense latch to the cache latch, and the cache latch transmits the data dumped by the data latch to a data I/O circuit. While the cache latch included in at least one of the plurality of first page buffers is performing a data transmit operation, the data latch included in at least one of the plurality of second page buffers performs a data dumping operation.

    Abstract: A method of programming a nonvolatile memory device including multi-level cells that store multi-bit data, includes performing a pre-programming operation that programs at least some of the multi-level cells to a plurality of intermediate states which are different from an erased state, and performing a main programming operation that programs the multi-level cells to a plurality of target states corresponding to the multi-bit data. At least some of the intermediate program states have threshold voltage distributions that partially overlap each other.

    Abstract: A nonvolatile memory device may include a plurality of memory planes and a plurality of plane-dedicated pad sets. The plurality of memory planes may include a plurality of memory cell arrays including nonvolatile memory cells and a plurality of page buffer circuits. Each of the plurality of page buffer circuits may be connected to ones of the nonvolatile memory cells included in each of the plurality of memory cell arrays through bitlines. A plurality of plane-dedicated pad sets may be connected to the plurality of page buffer circuits through a plurality of data paths respectively such that each of the plurality plane-dedicated pad sets is dedicatedly connected to each of the plurality of page buffer circuits. A bandwidth of a data transfer may be increased by reducing a data transfer delay and supporting a parallel data transfer, and power consumption may be decreased by removing data multiplexing and/or signal routing.
