  • Patent number: 9310424
    Abstract: A mechanism is provided for determining a modeled age of a mufti-core processor. For each core in a set of cores in the multi-core processor, a determination is made of a temperature, a voltage, and a frequency at regular intervals for a set of degradations and a set of voltage domains, thereby forming the modeled age of the multi-core processor. A determination is made as to whether the modeled age of the multi-core processor is greater than an end-of-life value. Responsive to the modeled age of the multi-core processor being greater than an end-of-life value, an indication is sent that the multi-core processor requires replacement.

  • Patent number: 8713490
    Abstract: A mechanism is provided for mitigating aging of a set of components in the data processing system. A modeled age of a component in the set of components is identified. A desired aging requirement for the component is identified and a determination is made as to whether the modeled age of the component is greater than the desired age of the component. Responsive to the modeled age of the component being greater than the desired age of the component, a policy is implemented to mitigate the aging of the component.

  • Patent number: 7890893
    Abstract: Disclosed is a design structure for a semiconductor chip structure that incorporates a localized, on-chip, repair scheme for devices that exhibit performance degradation as a result of negative bias temperature instability (NBTI). The repair scheme utilizes a heating element above each device. The heating element is configured so that it can receive transmission line pulses and, thereby generate enough heat to raise the adjacent device to a temperature sufficient to allow for performance recovery. Specifically, high temperatures (e.g., between approximately 300-400° C. or greater) in the absence of bias can accelerate the recovery process to a matter of seconds as opposed to days or months. The heating element can be activated, for example, on demand, according to a pre-set service schedule, and/or in response to feedback from a device performance monitor.

  • Patent number: 7541829
    Abstract: A method for correcting of asymmetric shifts in threshold voltage of transistors caused by effects such as negative-bias temperature instability (NBTI) during burn-in. The method may include providing logic patterns to an integrated circuit, such that devices that were stressed during burn-in are relaxed, and devices that suffered less stress during burn-in are stressed.

  • Publication number: 20090063061
    Abstract: A circuit, method, and computer readable medium that enables on-chip monitoring of transistor degradation. The circuit includes an on-chip reference ring oscillator electrically coupled to an on-chip reference counter. An on-chip stressed ring oscillator is electrically coupled to an on-chip test counter. A test enable input is electrically coupled with the reference counter, the test counter, and the reference ring oscillator. When the test enable input is asserted the reference ring oscillator places a bit sequence proportional to the reference ring oscillator frequency on the reference counter simultaneously while the stressed ring oscillator places bit sequence proportional to the stressed ring oscillator frequency on the test counter. A difference in bit sequence between the reference counter and the test counter is compared to determine a relative difference there between.

  • Patent number: 6563173
    Abstract: An SOI chip having an isolation barrier. The SOI chip includes a substrate, an oxide layer deposited on the substrate, and a silicon layer deposited on the oxide layer. A gate is deposited above the silicon layer. A first metal contact is deposited above the gate to form an electrical contact with the gate. Second and third metal contacts are deposited to form electrical contacts with the silicon layer. The isolation barrier extends through the silicon layer and the oxide layer, and partially into the substrate, to block impurities in the oxide layer outside the isolation barrier from diffusing into the oxide layer inside the isolation barrier. The isolation barrier surrounds the gate, the first metal contact, the second metal contact, and the third metal contact—which define an active chip area inside the isolation barrier. A method of manufacturing the SOI chip is also disclosed.

  • Patent number: 6437594
    Abstract: A monitor for detecting pass gate leakage in a silicon on insulator device and a method for using the same is described herein. A pulse generator supplies a signal to a set of buffers connected in parallel, which pass on a signal to the source side of a series of NFETs. The plurality of NFETs are ordered by increasing channel widths. The NFETs have grounded gates, and therefore will not pass current due to field effects. Each NFET is connected to a latch, and the latches are originally set to the same state. When the signal supplied to the NFET drops from high to low, pass gate leakage will occur through the channel of each NFET. If pass gate leakage through any given NFET is sufficient, the latch will change states. The latch output signal is sent to a shift register, which can be made to output information. By incorporating the monitor on the chip, pass gate leakage tolerances and specifications can be established in-line during manufacture.
