Electronic device, memory device, and method of operating memory device
The present technology provides an electronic device, a memory device, and a method of operating a memory device. The memory device includes a memory cell array including a variable resistance memory cell coupled to a first conductive line and a second conductive line, and a peripheral circuit configured to provide a write pulse or a read pulse to the variable resistance memory cell through the first conductive line. The write pulse is controlled to have one of a first polarity and a second polarity that are opposite to each other. The read pulse is controlled to have a polarity corresponding to a greater value of first and second amorphization start current values of the variable resistance memory cell, the first amorphization start current value being determined by a first pulse having the first polarity, the second amorphization start current value being determined by a second pulse having the second polarity.
