  • Patent number: 8278155
    Abstract: A reversible fuse structure in an integrated circuit is obtained through the implementation of a fuse cell having a short thin line of phase change materials in contact with via and line structures capable of passing current through the line of phase change material (fuse cell). The current is passed through the fuse cell in order to change the material from a less resistive material to a more resistive material through heating the phase change material in the crystalline state to the melting point then quickly quenching the material into the amorphous state. The reversible programming is achieved by passing a lower current through the fuse cell to convert the high resistivity amorphous material to a lower resistivity crystalline material. Appropriate sense-circuitry is integrated to read the information stored in the fuses, wherein said sense circuitry is used to enable or disable circuitry.

  • Patent number: 8112368
    Abstract: A method, apparatus and computer program product are provided to predict faults. Initially, a plurality of features are provided to a plurality of models. A subset of features is selected for each model. The plurality of features selected by a respective model is dependent upon a time scale associated with a respective model. As a result of their dependence upon different time scales, the plurality of selected features provided to a first model will differ from those provided to a second model. The plurality of models process the respective plurality of selected features. The outputs from the plurality of models are fused to generate a measure indicative of an impending fault. By providing different selected features to the models that are dependent upon the associated time scales and by then combining the outputs of the plurality of models, the resulting measure of an impending fault may accurately predict a fault well in advance of its occurrence.
