DATA PROGRAMMING METHOD OF NONVOLATILE MEMORY DEVICE AND APPARATUS THEREOF, AND DATA PROGRAMMING MODE CONFIGURING METHOD THEREFOR AND APPARATUS THEREFOR

摘要

The present invention relates a method and apparatus for programming data and a method and apparatus for setting a data programming mode therefor. The method for programming the data in a nonvolatile memory device according to one embodiment of the present invention comprises the steps of: determining the programming mode which is used in current data programming among at least two programming modes which regulate different verification voltages about a cell to be programmed based on set mode information; and programming the data according to the determined programming mode. According to the present invention, a loss of the programmed data is prevented after an SMD reflow process.
