Abstract:
A multilayer inductor is disclosed. The multilayer inductor includes a bottom magnetic layer having an external conductive pattern formed on a bottom surface thereof for connection to a substrate such as a printed circuit board. The bottom external conductive pattern includes signal/power contacts and first and second inductor electrodes. A top magnetic layer includes a top external conductive pattern having signal/power contacts and inductor electrode contacts. An inductor conductive pattern formed on the top surfaces of intermediate magnetic layers disposed between the top and bottom magnetic layers are electrically coupled to each other by means of through holes to form a spiral inductor element. The spiral inductor element is coupled to the first inductor electrode by means of a through hole formed in the bottom magnetic layer and to the second inductor electrode by means of power conductive traces formed on side surfaces of the multilayer inductor. Flux density reducing layers may be inserted directly above the bottom magnetic layer and directly below the top magnetic layer. Signal/power conductive traces formed on side surfaces of the multilayer inductor provide signal/power routing between the top magnetic layer signal/power contacts and the bottom magnetic layer signal/power contacts. The top external conductive pattern accommodates a semiconductor chip in a flip chip configuration.
Abstract:
A method in a computer system for retrieving data from one of multiple copies of the data is provided, referred to as the data management system. The data management system receives a request identifying at least one data object to be accessed. Then, the data management system queries a metabase to locate data copies that contain the identified at least one data object, wherein the data copies are created from similar source data, and wherein for each data copy the metabase contains an indication of the availability of the copy relative to other copies. Next, the data management system determines one of the located data copies to use to access the identified at least one data object, wherein the determination is made based on the indicated availability contained in the metabase for each of the located data copies. Then, the data management system accesses the identified at least one data object using the determined one of the located data copies.
