Abstract: A fuse for semiconductor devices, in accordance with the present invention, includes a cathode (104) including a first dopant type, and an anode (102) including a second dopant type where the second dopant type is opposite the first dopant type. A fuse link (106) connects the cathode and the anode and includes the second dopant type. The fuse link and the cathode form a junction (111) therebetween, and the junction is configured to be reverse biased relative to a cathode potential and an anode potential. A conductive layer (103) is formed across the junction such that current flowing at the junction is diverted into the conductive layer to enhance material migration to program the fuse.

Abstract: Embodiments of the present invention provide an authenticating service of a chip having an intrinsic identifier (ID). In a typical embodiment, an authenticating device is provided that includes an identification (ID) engine, a self-test engine, and an intrinsic component. The intrinsic component is associated with a chip and includes an intrinsic feature. The self-test engine retrieves the intrinsic feature and communicates it to the identification engine. The identification engine receives the intrinsic feature, generates a first authentication value using the intrinsic feature, and stores the authentication value in memory. The self-test engine generates a second authentication value using an authentication challenge. The identification engine includes a compare circuitry that compares the first authentication value and the second authentication value and generates an authentication output value based on the results of the compare of the two values.

Abstract: The present invention provides an authenticating service of a chip having an intrinsic identifier (ID). In a typical embodiment, an authenticating device is provided that includes an identification (ID) engine 104, a self-test engine 106, and an intrinsic component 108. The intrinsic component is associated with a chip and includes an intrinsic feature. The self-test engine retrieves the intrinsic feature and communicates it to the identification engine. The identification engine receives the intrinsic feature, generates a first authentication value using at least the intrinsic feature, and stores the authentication value in memory. A second authentication value is then generated using at least an authentication challenge 130. The identification engine includes a compare circuitry 116 that compares the first authentication value and the second authentication value and generates an authentication output value based on the results of the compare of the two values.
