Abstract
Program voltages of a non-volatile memory device are controlled variably according to a program/erase operation count. The non-volatile memory device includes a program voltage supply unit for applying a program voltage to a memory cell, a program/erase count storage unit for storing a total program/erase operation count of the non-volatile memory device, a program start voltage storage unit for storing levels of program start voltages to be differently supplied according to the program/erase operation count, and a program voltage controller for controlling the program start voltage according to the program/erase operation count.
