Patent number: 8650438Abstract: The present disclosure includes systems and techniques relating to solid state drive controllers. In some implementations, a device includes a buffer that holds a block of data corresponding to a command from a host. The command identifies the block of data and a logical sequence in which the identified block of data is to be transmitted. In response to the command, a data retriever included in the device retrieves the portions of the block of data from non-volatile memory units in a retrieval sequence that is different from the logical sequence. When the device receives multiple commands identifying multiple blocks of data, the device services the commands in parallel by retrieving portions of blocks of data identified by both commands.Type: GrantFiled: July 23, 2010Date of Patent: February 11, 2014Assignee: Marvell World Trade Ltd.Inventors: Cheng Kuo Huang, Siu-Hung Fred Au, Lau Nguyen, Perry Neos

Patent number: 8263991Abstract: A light-emitting gallium nitride-based III-V group compound semiconductor device and a manufacturing method thereof are disclosed. The light emitting device includes a substrate, a n-type semiconductor layer over the substrate, an active layer over the n-type semiconductor layer, a p-type semiconductor layer over the active layer, a conductive layer over the p-type semiconductor layer, a first electrode disposed on the conductive layer and a second electrode arranged on exposed part of the n-type semiconductor layer. A resistant reflective layer or a contact window is disposed on the p-type semiconductor layer, corresponding to the first electrode so that current passes beside the resistant reflective layer or by the contact window to the active layer for generating light. When the light is transmitted to the conductive layer for being emitted, it is not absorbed or shielded by the first electrode. Thus the current is distributed efficiently over the conductive layer.Type: GrantFiled: November 13, 2007Date of Patent: September 11, 2012Assignee: Formosa Epitaxy IncorporationInventors: Kuo-Chin Huang, Shyi-Ming Pan, Cheng-Kuo Huang, Chi-Yang Chuang, Fen-Ren Chien
