METHOD OF WRITING DATA IN NONVOLATILE MEMORY DEVICE METHOD OF ERASING DATA IN NONVOLATILE MEMORY DEVICE AND NONVOLATILE MEMORY DEVICE PERFORMING THE SAME

摘要

According to the present invention, in a data storage method of a nonvolatile memory device, the nonvolatile memory device comprises a plurality of cell strings, in which a plurality of memory cells are disposed in a vertical direction, respectively. A program target page connected to one of a plurality of word lines is divided into a plurality of subpages each of which includes memory cells that are not physically adjacent. A program operation is sequentially performed on each of the plurality of subpages. A program verification operation is performed as a whole on the program target page including the plurality of subpages.
