Abstract: Provided are a non-volatile memory device and a method of operating the same. The non-volatile memory device includes a substrate, a plurality of word lines extending in a first direction on the substrate, a plurality of ferroelectric patterns respectively provided on the word lines, a blocking insulating film covering the ferroelectric patterns, a plurality of bit line pairs including a first bit line and a second bit line extending in a second direction crossing the word lines and the ferroelectric patterns on the blocking insulating film and intersecting the first direction, and a channel pattern provided between the first bit line and the second bit line of each of the bit line pairs on the blocking insulating film, wherein the channel pattern has an ambipolar conduction characteristic.
