Claim 11:
12. A method for programming at least one selected memory cell of a plurality of memory cells included in a non-volatile memory device, each of the plurality of memory cells being connected to a word line of a plurality of word lines and a bit line of a plurality of bit lines, the non-volatile memory device including a memory cell region including a first metal pad and the plurality of memory cells, the non-volatile memory device further including a peripheral region including a second metal pad and a voltage generator the peripheral region connected to the plurality of memory cells through the first metal pad and the second metal pad, the method comprising:
performing a first program operation based on a first condition, the first program operation including:
generating a first bit line voltage, a first program voltage, a first adjacent voltage, and a first pass voltage by the voltage generator, wherein voltage levels and voltage application times of the first bit line voltage, the first program voltage, the first adjacent voltage, and the first pass voltage correspond to the first condition; and
providing the first bit line voltage to a selected bit line connected to the at least one selected memory cell, providing the first program voltage to a selected word line connected to the at least one selected memory cell, providing the first adjacent voltage to word lines immediately adjacent to the selected word line, and providing the first pass voltage to word lines not immediately adjacent to the selected word line;

performing a first verify operation based on the first condition, including generating a first verify voltage by the voltage generator and providing the first verify voltage to the selected word line;
performing a second program operation based on a second condition, the second program operation including:
generating a second bit line voltage, a second program voltage, a second adjacent voltage, and a second pass voltage by the voltage generator, wherein voltage levels and voltage application times of the second bit line voltage, the second program voltage, the second adjacent voltage, and the second pass voltage correspond to the second condition; and
providing the second bit line voltage to the selected bit line, providing the second program voltage to the selected word line, providing the second adjacent voltage to the word lines immediately adjacent to the selected word line, and providing the second pass voltage to the word lines not immediately adjacent to the selected word line; and

performing a second verify operation based on the second condition, including generating a second verify voltage by the voltage generator and providing the second verify voltage to the selected word line,
wherein the first condition is different from the second condition, and wherein the at least one selected memory cell is formed perpendicularly to a substrate included in the non-volatile memory device.
