    摘要: A method of operating a nonvolatile memory device including a plurality of memory cells is provided. A default read operation is performed on a page using a default read voltage set to generate default raw data. If error bits of the default raw data are not corrected, a plurality of low-level read operations is performed on the page using a plurality of read voltage sets to generate a plurality of low-level raw data. Each read voltage set is different from the default voltage set. A read voltage set is selected from the plurality of read voltage sets as a starting voltage set, according to each low-level raw data. A high-level read operation using the selected starting voltage set is performed on the page to generate high-level raw data.

    摘要: A nonvolatile memory device includes a memory cell array having multiple memory blocks. Each memory block includes memory cells arranged at intersections of multiple word lines and multiple bit lines. At least one word line of the multiple word lines is included in an upper word line group and at least one other word line of the multiple word lines is included in a lower word line group. The number of data bits stored in memory cells connected to the at least one word line included in the upper word line group is different from the number of data bits stored in memory cells connected to the at least one other word line included in the lower word line group.
