Abstract
In a method of operating a non-volatile memory device, a bit line is precharged to a positive voltage, which is input through a common source line of cell strings of memory cells, according to a degree in which a selected memory cell has been programmed. Data according to a voltage level of a sensing node, which is changed according to a level of the voltage of the bit line, is stored in a first latch of a page buffer. The data stored in the first latch is transferred to a second latch through the sensing node.
