A memory device includes an anti-fuse cell array including a plurality of anti-fuse cells. Each anti-fuse cell includes a first cell transistor connected to a common node, a second cell transistor connected to the common node, and an access transistor connected to the common node. The first cell transistor is configured to store data and the second cell transistor is configured to store data when the first cell transistor has defect data.
