NONVOLATILE MEMORY DEVICE, METHOD OF PROGRAMMING THE SAME AND MEMORY SYSTEM INCLUDING THE SAME

摘要

PURPOSE: A nonvolatile memory device, a method of programming the same and a memory system including the same are provided to improve reliability by reducing a coupling effect which is generated in programming. CONSTITUTION: In a nonvolatile memory device, a method of programming the same and a memory system including the same, program data is programmed in selected memory cells. Erased memory cells are programmed to a second erase state. The program of program data is performed through an ISPP(Incremental Step Pulse Program) The Erased memory cells is performed through the ISPP(Incremental Step Pulse Program).
