    Abstract: Disclosed is an integrated circuit (IC) chip having an on-chip usable life depletion meter. This meter incorporates programmable bits, which represent units of usable life. These programmable bits are sequentially ordered from an initial programmable bit to a last programmable bit and are automatically programmed in order, as the expected usable life of the IC chip is depleted. These programmable bits are readable to determine the remaining usable life of the IC chip. Also disclosed is a method that uses the on-chip usable life depletion meter. In the method, the remaining usable life of an IC chip, once known, is used either as the basis for allowing re-use of the IC chip (e.g., for a non-critical application and when the remaining usable life is sufficient) or as the basis for preventing re-use of the IC chip (e.g., for a critical application or when the remaining usable life is insufficient).

  • Patent number: 9766966
    Abstract: Systems and methods are provided for optimizing operation of an integrated circuit. In one implementation, a system is provided for optimizing operation of an integrated circuit by adjusting an operational parameter of the integrated circuit based on a reference count stored in non-volatile memory fabricated on the integrated circuit. In another implementation, a method is provided for optimizing operation of an integrated circuit by generating, during operation of the integrated circuit, a first oscillator count of an oscillator, comparing the first oscillator count with at least one reference count stored on the integrated circuit, and activating, a control circuit to adjust an operational parameter of the integrated circuit based on a result of the comparison.

  • Patent number: 9728509
    Abstract: Structures that include an identification marking and fabrication methods for such structures. A chip is formed within a usable area of a wafer, and a marking region is formed on the wafer. The marking region is comprised of a conductor used to form a last metal layer of an interconnect structure for the chip. The identification marking is formed in the conductor of the marking region. After the identification marking is formed, a dielectric layer is deposited on the marking region. The dielectric layer on the marking region is planarized.

  • Patent number: 9720043
    Abstract: A method of testing a fuse in apparatus for monitoring electrical insulation surrounding first and second electrical conductors in a cable, the fuse being connected to the conductors, comprises: applying an electrical signal, with respect to a reference, to the fuse from a source; obtaining a value for the resistance of the insulation with respect to the reference; determining if the resistance value is greater than a fuse test resistance threshold and, if it is, causing the application of the signal to cease; and monitoring the decay of the signal to determine if the time for it to decay below a set value exceeds a set time limit, indicative of the fuse being satisfactory, or is less than the limit indicative of the fuse being blown.

  • Patent number: 9696920
    Abstract: A memory device includes a memory component that store data. The memory device also includes a processor that receives a signal indicating that the memory component is coupled to the processor and retrieves information from the memory component. The information may include one or more algorithms capable of being performed by the memory component. The processor may then receive one or more packets associated with one or more data operations regarding the memory component. The processor may then perform the one or more data operations by using the memory component to employ the one or more algorithms.

  • Patent number: 9690927
    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: A contact element (25) (electroformed product) is produced by electroforming. The contact element (25) has a surface on which an insulating film (28) having been formed by use of a dry film resist or the like is provided. In a process of producing the contact element (25), the insulating film (28) is provided after a step of producing the contact element 25. This makes it possible to provide electroformed components configured so that respective electroformed products (contact terminals) are arranged at narrow pitches while maintaining electrical insulation of the electroformed products from each other.
