NONVOLATILE MEMORY DEVICE, NOVOLATILE MEMORY SYSTEM, PROGRAM METHOD THEREOF, AND OPERATION METHOD OF CONTROLLER CONTROLLING THE SAME

摘要

PURPOSE: A non-volatile memory device, a non-volatile memory system including thereof, a program method thereof, and a controller operation method controlling thereof are provided to perform the program operation by reducing the program disturbance. CONSTITUTION: A flash memory device (1100) comprises a coupling program controlling unit (1165). A first memory cell programs a first data pattern. A second memory cell programs by using the program voltage. By using the verification voltage which corresponds to the first data pattern, the programming of the first data pattern of the first memory cell is verified. If the verification result of the first memory cell is 'pass', the program of the second memory cell is completed.
