A non-volatile memory device includes a plurality of unit cells. Each unit cell includes lower and upper electrodes over a substrate, a conductive organic material layer between the lower and the upper electrodes, and a nanocrystal layer located within the conductive organic material layer, wherein the nanocrystal layer includes a plurality of nanocrystals surrounded by an amorphous barrier. The unit cell receives a plurality of voltage ranges to perform a plurality of operations. A read operation is performed when an input voltage is in a first voltage range. A first write operation is performed when the input voltage is in a second voltage range higher than the first voltage range. A second write operation is performed when the input voltage is in a third voltage range higher than the second voltage range. An erase operation is performed when the input voltage is higher than the third voltage range.

Provided is a method of driving a display panel having a charge trap device and an organic light emitting diode (OLED). The charge trap device includes a nanocrystal layer. The nanocrystal layer includes nanocrystals, which are crystallized and dispersed, and a barrier layer, which buries the nanocrystals. When a program voltage is applied, charges are trapped in the nanocrystals, and the OLED emits light at a predetermined luminance with the application of a read voltage. Data signals are sequentially applied to all pixels of the display panel to express desired grayscales. The pixels of the display panel receive the read voltage and emit light at the same time.
