  • Patent number: 9397552
    Abstract: A system including a converter and a snubber circuit. The converter converts an alternating current voltage into a direct current voltage and outputs the direct current voltage across an inductance and a switch connected in series. The inductance has a center tap connected to a node, which is connected to a load. In response to the switch being turned on, a first current flows through the inductance and the switch. In response to the switch being turned off, a second current flows from the node to the load. The snubber circuit is connected across the node and a junction of the inductance and the switch. In response to the switch being turned off, the snubber circuit receives a third current from the junction, and supplies a first portion of the third current to the node. The second current and the first portion of the third current flow through the load.

  • Patent number: 9323688
    Abstract: A data access system including a storage device and a processor, which includes one or more levels of cache (LOC). In response to data required by the processor not being within the LOC, the processor generates a physical address to be accessed within the storage device in order to retrieve the data. The storage device includes a main memory and a cache module, which is configured as a final level of cache (FLOC) to be accessed by the processor prior to accessing the main memory. The cache module includes a controller that, in response to the data not being cached within the LOC, converts the physical address into a virtual address within the FLOC. The FLOC uses the virtual address to determine whether the data is within the FLOC. If the data is not within the FLOC, the cache module or the processor retrieves the data from the main memory.
