In one aspect, an apparatus includes an N− well and an anti-fuse cell formed on the N− well. The anti-fuse cell includes a drain P+ diffusion deposited in the N− well, a source P+ diffusion deposited in the N− well, and an oxide layer deposited on the N− well and having an overlapping region that overlaps the drain P+ diffusion. A control gate is deposited on the oxide layer. A data bit of the anti-fuse cell is programmed when a voltage difference between the control gate and the drain P+ diffusion exceeds a voltage threshold of the oxide layer and forms a leakage path from the control gate to the drain P+ diffusion. The leakage path is confined to occur in the overlapping region."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"CMOS anti-fuse cell","description":"A CMOS anti-fuse cell is disclosed.
