  • Patent number: 9564883
    Abstract: Toggling functional critical path timing sensors measure delays in toggling functional critical paths that are replicas of actual critical paths or representations of worst-case delay paths. A Toggle flip-flop or Linear-Feedback-Shift Register (LFSR) drives high-transition-density test patterns to the toggling functional critical paths. When a toggling functional critical path's delay fails to meet set-up timing requirement to a next register, the toggling functional critical path timing sensors signal a controller to increase VDD. When no failures occur over a period of time, the controller decreases VDD. A margin delay buffer adds a delay to the toggling functional critical path before being clocked into an early capture flip-flop. A reference register receives the test pattern without the delay of the toggling functional critical path, and an exclusive-OR (XOR) gate compares outputs of reference and early capture flip-flops to generate timing failure signals to the controller.

  • Patent number: 9564884
    Abstract: Toggling functional critical path timing sensors measure delays in toggling functional critical paths that continuously receive patterns from an aging pattern generator. Wear is accelerated. A margin delay adjustment controller sweeps margin delays until failures occur to measure delays. The margin delay is then adjusted in functional critical path timing sensors that add the margin delay to functional critical paths that carry user data or chip controls during normal operation. When the path delays fail to meet requirements, the functional critical path timing sensors signal a controller to increase VDD. When no failures occur over a period of time, the controller decreases VDD. Wear on the toggling functional critical paths is accelerated using both toggle and low-transition-density patterns. Circuit aging is compensated for by increasing margin delays to timing sensors.

    Abstract: A random intrinsic chip ID generation employs a retention fail signature. A 1st and 2nd ID are generated using testing settings with a 1st setting more restrictive than the 2nd, creating more fails in the 1st ID bit string that includes 2nd ID bit string. A retention pause time controls the number of retention fails, adjusted by a BIST engine, wherein the fail numbers satisfy a predetermined fail target. Verification confirms whether the 1st ID includes the 2nd ID bit string, the ID being the one used for authentication. Authentication is enabled by a 3rd ID with intermediate condition such that 1st ID includes 3rd ID bit string and 3rd ID includes 2nd ID bit string. The intermediate condition includes a guard-band to eliminate bit instability problem near the 1st and 2nd ID boundary. The intermediate condition is changed at each ID read operation, resulting in a more secure identification.

  • Publication number: 20120007624
    Abstract: A semiconductor system for identifying stacked chips includes a first semiconductor chip and a plurality of second semiconductor chips. The first semiconductor chip generates a plurality of counter codes by using an internal clock or an external input clock and transmits slave address signals and the counter codes through a through-chip via. The second semiconductor chips are given corresponding identifications (IDs) by latching the counter codes for a predetermined delay time, compare the latched counter codes with the slave address signals, and communicate data with the first semiconductor chip through the through-chip via according to the comparison result.

  • Publication number: 20110309852
    Abstract: Methods and apparatus are disclosed to simultaneously, wirelessly test semiconductor components formed on a semiconductor wafer. The semiconductor components transmit respective outcomes of a self-contained testing operation to wireless automatic test equipment via a common communication channel. Multiple receiving antennas observe the outcomes from multiple directions in three dimensional space. The wireless automatic test equipment determines whether one or more of the semiconductor components operate as expected and, optionally, may use properties of the three dimensional space to determine a location of one or more of the semiconductor components. The wireless testing equipment may additionally determine performance of the semiconductor components by detecting infrared energy emitted, transmitted, and/or reflected by the semiconductor wafer before, during, and/or after a self-contained testing operation.

  • Patent number: 7956626
    Abstract: A circuit with switchable functionality has a first integrated circuit, which has, in a first operating mode, full functionality and which has, in at least one other operating mode, a functionality which is reduced in comparison with the full functionality. The circuit further has an output terminal to which a coupling element can be coupled, an identification device which identifies whether a first supply potential has been applied to the output terminal via the coupling element and in this case produces a status signal with a first value and otherwise produces a status signal with a second value, a setting device, which sets the full or reduced functionality as a function of the value of the status signal in the first integrated circuit. The invention also relates to an electronic component having such a circuit arrangement.

  • Patent number: 7902845
    Abstract: There is established an easier inspection method with which it is not required to set up probes on wires. Also, there is provided an inspection apparatus using this inspection method. With the inspection apparatus or inspection method, primary coils of an inspection substrate and secondary coils of a device substrate are superimposed on each other so that a certain space is maintained therebetween. An AC signal is inputted into the primary coils, thereby generating an electromotive force in each secondary coil by electromagnetic induction. Then, each circuit provided on the device substrate is driven using the electromotive force and information possessed by an electromagnetic wave or electric field generated in this circuit is monitored, thereby detecting each defective spot.
