    摘要: Methods and circuits for undiscoverable physical chip identification are disclosed. Embodiments of the present invention provide an intrinsic bit element that comprises two transistors. The two transistors form a pair in which one transistor has a wide variability in threshold voltage and the other transistor has a narrow variability in threshold voltage. The wide variability is achieved by making a transistor with a smaller width and length than the other transistor in the pair. The variation of the threshold voltage of the wide variability transistor means that in the case of copies of intrinsic bit elements being made, some of the “copied” wide variability transistors will have significantly different threshold voltages, causing some of the intrinsic bit elements of a copied chip to read differently than in the original chip from which they were copied.

    摘要: A method of fabricating a memory device is provided that may begin with forming a layered gate stack overlying a semiconductor substrate and patterning a metal electrode layer stopping on the high-k gate dielectric layer of the layered gate stack to provide a first metal gate electrode and a second metal gate electrode on the semiconductor substrate. In a next process sequence, at least one spacer is formed on the first metal gate electrode overlying a portion of the high-k gate dielectric layer, wherein a remaining portion of the high-k gate dielectric is exposed. The remaining portion of the high-k gate dielectric layer is etched to provide a first high-k gate dielectric having a portion that extends beyond a sidewall of the first metal gate electrode and a second high-k gate dielectric having an edge that is aligned to a sidewall of the second metal gate electrode.

    摘要: An antifuse has first and second semiconductor regions having one conductivity type and a third semiconductor region therebetween having an opposite conductivity type. A conductive region contacting the first region has a long dimension in a second direction transverse to the direction of a long dimension of a gate. An antifuse anode is spaced apart from the first region in the second direction and a contact is connected with the second region. Applying a programming voltage between the anode and the contact with gate bias sufficient to fully turn on field effect transistor operation of the antifuse heats the first region to drive a dopant outwardly, causing an edge of the first region to move closer to an edge of the second region and reduce electrical resistance between the first and second regions by an one or more orders of magnitude.
