  • Patent number: 7233162
    Abstract: Systems for testing a plurality of integrated circuits at a plurality of frequencies and voltages is disclosed. In one embodiment, a plurality of integrated circuits is tested at least once within a predetermined set of combinations of frequencies and voltages. If the integrated circuit fails testing within any combination of a frequency and voltage within the predetermined set, the integrated circuit is retested at a different predetermined set of combinations of frequencies and voltages. If the integrated circuit fails testing within any combination of a frequency and voltage within the different predetermined set, the integrated circuit is discarded.

  • Patent number: 7157924
    Abstract: An on-die device is provided to measure/detect voltage fluctuations. This may include a control unit to generate differential reference signals (such as differential current signals), a first detector unit and a second detector unit. The differential reference signals may be generated based on a Vcc reference signal and a Vss reference signal. The first detector unit may receive the differential reference signals from the control unit and may receive first voltage signals (also called monitored signals) from a first device under test (DUT) located on the die or from a first area on the die. The first detector unit may provide (or output) a first signal indicative of a voltage fluctuation (voltage droop or overshoot) of the first voltage signals. The second detector unit may receive the differential reference signals from the control unit and may receive second voltage signals (also called monitored signals) from a second device under test (DUT) located on the die.

  • Patent number: 7117114
    Abstract: An on-die temperature control variable is provided to throttle a thermal actuator for cooling an integrated circuit. The integrated circuit includes a storage element to hold the temperature control variable. A temperature sensor is thermally coupled to the integrated circuit to sense an operating temperature of the integrated circuit. A thermal controller is communicatively coupled to the storage element and to the temperature sensor. The thermal controller throttles the thermal actuator when the temperature sensor indicates that the operating temperature of the integrated circuit is below the temperature control variable.

  • Publication number: 20060033522
    Abstract: Some embodiments of the invention include apparatus and systems having integrated circuits. Terminals or pins of the integrated circuits are configured to be driven to a state, to be floated for a time interval, and to be measured to determine the state of the terminals after the time interval. The measurement involves sampling the RC time constant of leakage current of the terminals. Other embodiments are described and claimed.
