Abstract

Disclosed are a programming method and a nonvalatile memory device. The method includes receiving programming data to be programmed in a memory device unit; reading the memory device unit to determine an erasure state and at least one programming state; executing state reading operation, wherein the at least one programming state is used by a plurality of states to read voltage; and reading operation results according to states and using a plurality of verification voltage with different levels to program programming data in the memory device unit. Also disclosed is a method for using a plurality of verification voltage, in which verification voltage is selected based on other characteristic elements which can influence threshold voltage offset or represent data of the memory device unit after programming.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2011-0104753 filed on Oct. 13, 2011, which is hereby incorporated by reference in its entirety. technical field [0003] The inventive concepts described herein relate to semiconductor memory devices, and more particularly, to methods of programming nonvolatile memory devices and memory systems including the same. Background technique [0004] Semiconductor memory devices may be manufactured using semiconductors such as silicon (Si), germanium (Ge), gallium arsenide (GaAs), indium phosphide (InP), and the like. Semiconductor memory devices are classified into volatile memory devices and nonvolatile memory devices. [0005] Volatile memory devices may lose stored data when they are turned off or lose power. Volatile memory devices include static RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), and others. Nonvolatile memory devices retain...
