Patent ID: 6985387

Claim:
A one-time programming memory element capable of being manufactured in a 0.13 μm or below CMOS technology, comprising: a capacitor having an oxide layer capable of passing direct gate tunneling current; a write circuit, including a first switch coupled to said capacitor, said first switch including a first switch transistor connected between a first terminal of said capacitor and a first voltage, and a second switch coupled to said capacitor, said second switch including a second switch transistor connected between a second terminal of said capacitor opposing said first terminal and a second voltage; and a read circuit coupled to said capacitor, wherein said capacitor is one-time programmable as an anti-fuse by application of a program voltage across said oxide layer via said write circuit to cause direct gate tunneling current to rupture said oxide layer to form a conductive path having resistance of approximately hundreds of ohms or less.
