DATA STORAGE INCLUDING RECOVERY FUNCTION FOR THRESHOLD VOLTAGE DISTRIBUTION CHANGE OF MEMORY CELLS ACCORDING TO APPLYING SURFACE MOUNTING TECHNOLOGY AND OPERATING METHOD THEREOF

摘要

In the data storage programming method according to an embodiment of the present invention, before applying the surface mount technology to the plurality of nonvolatile memories, memory cells of at least one nonvolatile memory among the plurality of nonvolatile memories are set as a first reference. and pre-programming with a first verify voltage greater than the voltage. According to an embodiment of the present invention, since the nonvolatile memory is pre-programmed in consideration of the change in threshold voltage distribution generated by applying the surface mount technology, boot fail can be prevented.
