摘要:
A one-time programming memory element, capable of being manufactured in a 0.13 μm or below CMOS technology, having a capacitor, or transistor configured as a capacitor, with an oxide layer capable of passing direct gate tunneling current, and a switch having a voltage tolerance higher than that of the capacitor/transistor, wherein the capacitor/transistor is one-time programmable as an anti-fuse by application of a voltage across the oxide layer via the switch to cause direct gate tunneling current to thereby rupture the oxide layer to form a conductive path having resistance of approximately hundreds of ohms or less.
