1. A method of testing a non-volatile memory device, the non-volatile memory device including a memory area, the memory area including memory cells that are connected to a plurality of word lines, the method comprising:
selecting, by the non-volatile memory device, one of a plurality of program loop frequencies as a first value, the plurality of program loop frequencies corresponding to the plurality of word lines; determining, by the non-volatile memory device, a second value based on a number N of the plurality of program loop frequencies, where the number N is a natural number that is equal to or greater than two; determining, by the non-volatile memory device, a characteristic value of the memory area based on the first and second values; and determining, by the non-volatile memory device, whether the memory area is defective based on a reference value and the characteristic value. |
