  • Patent number: 8935464
    Abstract: A system including an interface module to interface a solid-state disk controller to a computing device. A memory control module exchanges data with the computing device via the interface module and caches the data in a solid-state memory controlled by the solid-state disk controller. A network interface module communicates with the computing device via the interface module and interfaces the computing device to a wireless network. A crossbar module has a master bus (Mbus) interface bridged to an advanced high-performance bus (AHB). A memory communicates with one or more of the network interface module and the crossbar module via one or more of the Mbus interface and the AHB. In response to data being cached from the computing device to the solid-state memory or data cached in the solid-state memory being output to the computing device, the network interface module buffers data received from the wireless network in the memory.

  • Publication number: 20140306349
    Abstract: Some implementations provide an interposer that includes a substrate, a via in the substrate, and an oxidation layer. The via includes a metal material. The oxidation layer is between the via and the substrate. In some implementations, the substrate is a silicon substrate. In some implementations, the oxidation layer is a thermal oxide formed by exposing the substrate to heat. In some implementations, the oxidation layer is configured to provide electrical insulation between the via and the substrate. In some implementations, the interposer also includes an insulation layer. In some implementations, the insulation layer is a polymer layer. In some implementations, the interposer also includes at least one interconnect on the surface of the interposer. The at least one interconnect is positioned on the surface of the interposer such that the oxidation layer is between the interconnect and the substrate.
