Claim 12:
13. An anti-fuse circuit, comprising an anti-fuse device and a diode,
wherein an anode of the anti-fuse device is electrically connected with a bit line, a cathode of the anti-fuse device is electrically connected with an anode of the diode, and a cathode of the diode is electrically connected with a word line,
wherein the diode comprises:
a well region of a second conductive type located in a substrate, the well region of the second conductive type being the cathode of the diode; and
a doped region of a first conductive type located in the well region of the second conductive type, the doped region of the first conductive type being the anode of the diode.
