Abstract
A nonvolatile memory device preventing a program disturb, a program method thereof and a memory system including the nonvolatile memory device and the program method. The nonvolatile memory device includes a memory cell array; first and second word lines connected to a NAND string in the memory cell array; a third word line connected to the NAND string, the third word line being disposed between the first and second word lines; a temperature sensor configured to measure the temperature of the nonvolatile memory device; and a voltage generator configured to generate first and second pass voltages and a program voltage, and the voltage level of at least one of the first and second pass voltages is controlled according to the measured temperature. When a program operation is performed, the program voltage is applied to the third word line, the first pass voltage is applied to the first word line, the second pass voltage is applied to the second word line.
