A one-time programming memory element, capable of being manufactured in a 0.13
m or below CMOS technology, having a capacitor, or transistor configured
as a capacitor, with an oxide layer capable of passing direct gate tunneling current.
Also included is a write circuit, having first and second switches coupled to the
capacitor, and a read circuit also coupled to the capacitor. The capacitor/transistor
is one-time programmable as an anti-fuse by application of a program voltage across
the oxide layer via the write circuit to cause direct gate tunneling current to
rupture the oxide layer to form a conductive path having resistance of approximately
hundreds of ohms or less.
