  • Patent number: 8468366
    Abstract: Disclosed is a method for storing an identifier in a first station having a secure non-volatile data store protected by cryptographic data, an identifier flag for indicating that the identifier has been written to the secure data store, and an authenticated trust agent that prohibits writing of an identifier to the secure data store if the identifier flag is set. In the method, the identifier is written to the secure non-volatile data store, wherein the identifier written to the secure data store is encrypted using the cryptographic data. The identifier flag is irreversibly set after writing the identifier to the secure data store so that the trust agent prohibits another write of an identifier to the secure data store.

  • Publication number: 20080263117
    Abstract: A secure seeding and reseeding scheme is provided for pseudorandom number generators by using a pre-stored initialization seed. This scheme initializes a pseudorandom number generator into an unknown state even when entropy collection is unavailable. A primary seed file and a shadow seed file are maintained with initialization seed information in a secure file system. If the primary seed file is corrupted, the pseudorandom number generator is seeded with the content of the shadow seed file. Additionally, a trusted timer or clock may be mixed with the pre-stored initialization seed to add entropy even when the pre-stored seed information has been compromised.

  • Publication number: 20070150197
    Abstract: Method and apparatus to control delay between lanes in an I/O interface is disclosed. To control the delay between the lanes in the I/O system a programmed delay may be determined and introduced between the lanes. For this purpose the effective time “T” of the lanes is determined. The number of lanes “N” in the I/O interface is identified. The programmed lane to lane delay “D” is determined and a delay circuit having the programmed delay may be introduced between the lanes to reduce AC peak to peak noise in the I/O system.

  • Publication number: 20060267216
    Abstract: A series of plated through hole (PTH) vias are interconnected by traces that alternate between a top surface and a bottom surface of a dielectric board. The PTH vias in the series can be positioned to create a collinear inductive filter, a coil-type inductive filter, or a transformer. Multiple, electrically isolated series of interconnected PTH vias can be used as a multi-phase inductive filter in one embodiment. In another embodiment, multiple series of interconnected PTH vias are electrically connected by a linking portion of conductive material, resulting in a low-resistance inductive filter. Ferromagnetic material patterns can be embedded in the dielectric board to enhance the inductive characteristics of the interconnected via structures. In one embodiment, a closed-end pattern is provided with two series of interconnected vias coiling around the pattern, resulting in an embedded transformer structure.

  • Publication number: 20060261465
    Abstract: Trace configurations for carrying high-speed digital differential signals provide for reduced conduction loss and improved signal integrity. In one embodiment, a circuit board has a first set of conductive traces disposed on non-conductive material, and a second set of conductive traces parallel to the first set and disposed within the conductive material. The second set is separated from the first set by non-conductive material. Corresponding traces of the first and second sets may be in a stacked configuration. In other embodiments, conductive material may be provided between corresponding traces of the first and second sets resulting in an “I-shaped” or “U-shaped” cross-section. In yet other embodiments, the trace configurations have “T-shaped” and “L-shaped” cross-sections.

  • Publication number: 20060256502
    Abstract: A multilayer capacitor comprises separate terminals on at least three sides, and on as many as six sides. The capacitor can be fabricated in a large number of different configurations, types, and sizes, depending upon the target application. The separate terminals that are disposed on different sides of the capacitor can be readily coupled to a variety of different adjacent conductors, such as die terminals (including bumpless terminals or bars), IC package terminals (including pads or bars), and the terminals of adjacent discrete components. Methods of fabrication, as well as application of the capacitor to an electronic assembly, are also described.

  • Patent number: 6584685
    Abstract: A system and method for embedding power and ground planes in a pin grid array (PGA) socket is provided. Integrated circuit pins are inserted into multiple insertion holes of varying dimensions in the power and ground planes. When the cover of the socket is slidably moved, power pins touch the power plane and ground pins touch the ground plane. Decoupling capacitors are also affixed to the substrate. Thus, the power delivery performance of the overall central processing unit (CPU) package is improved. Moreover, the power and ground planes enhance the mechanical strength of the socket which reduces warpage.
