    摘要: A method of operating a memory system including a non-volatile memory device and a memory controller controlling the non-volatile memory device, includes reading data from a memory cell array in a unit of a page which includes a plurality of sectors; performing error correction decoding on the read data in a unit of a sector of the page; selecting at least one target sector which includes at least one uncorrectable error and selecting at least one pass sector wherein all errors of the pass sector are correctable by the error correction decoding; inhibiting precharging of bit-lines connected to the at least one pass sector while precharging target bit lines connected to the at least one target sector; and performing a read retry operation for data in the at least one target sector.

    摘要: An operating method of a nonvolatile memory system includes receiving a read request for at least one page from a host. Upon receiving the read request, read voltages are adjusted using a read history table to perform a first read operation in which data stored at the nonvolatile memory is read. An optimal read voltage set is detected when data read according to the first read operation includes an uncorrectable error, and a second read operation is performed in which the stored data is read based on the detected optimal read voltage set. The read history table is updated based on a reliability parameter indicating a characteristic of the nonvolatile memory, a characteristic of the data at the first or second read operation, the optimal read voltage, or the read history table.

    摘要: A method for driving a nonvolatile memory device includes performing an erase operation with respect to a plurality of memory cells, stopping the erase operation by a suspend command, calculating a residual time of the erase operation that has not yet been performed, performing a first operation, comparing a first vacant time between a completion time point of the first operation and a start time point of a second operation with the residual time, performing the erase operation that has not yet been performed if the residual time is equal to or shorter than the first vacant time, and performing the second operation if the residual time is longer than the first vacant time.

    摘要: The inventive concept relates to a nonvolatile memory device and a method of detecting a defective word line. The method includes executing a defective word line detection operation using a program/erase voltage applied to a selected word line, wherein the defective word line detection operation determines whether or not the selected word line is defective in relation to respective word line voltage responses for the first and second segments during execution of the program/erase operation.
