Abstract:
An anti-fuse cell includes a control device and an anti-fuse element is introduced. The control device includes a source node, a drain node and a gate node, wherein the gate node is electrically coupled to a word line and the drain node is electrically coupled to a bit line. The anti-fuse element includes a first conductive layer, a second conductive layer and a dielectric layer, wherein the dielectric layer is disposed between the first conductive layer and the second conductive layer. The second conductive layer of the anti-fuse element is physically stacked upon a conductive layer and electrically connected to the source node of the control device, and first conductive layer is electrically coupled to a program line through a via. An anti-fuse cell having multiple anti-fuse elements and a chip having a plurality of anti-fuse cells are also introduced.
