Abstract
A nonvolatile memory device includes a memory cell comprising a first variable resistor having one end connected to a first node, and the other end connected to a second node through a cell transistor; and a reference cell comprising a second variable resistor having one end connected to a third node, and the other end connected to a fourth node through a reference cell transistor, wherein gates of the cell transistor and the reference cell transistor are connected to a word line. Directions of a first read current flowing in the memory cell and a direction of a second read current flowing in the reference cell are opposite to each other.
