Patent number: 11843459Abstract: The present disclosure provides an encoding and decoding device implementing an improved forward error correction (FEC) coding/decoding method. In particular, the encoding device is configured to encode a stream of data symbols using a spatially coupled code (e.g. staircase codes, braided block codes or continuously interleaved block codes), wherein at least one generalized error location (GEL) code is used as a component code of the spatially coupled code. Accordingly, the decoding device is configured to decode a sequence of encoded symbol blocks using a spatially coupled code, wherein at least one GEL code is used as a component code of the spatially coupled code. Thereby, a suitable spatially coupled FEC code that allows for very low-latency, high-throughput, high-rate applications with a low-complexity decoding procedure, and allows for mitigation of the error-floor, is designed.Type: GrantFiled: June 10, 2022Date of Patent: December 12, 2023Assignee: Huawei Technologies Co., Ltd.Inventors: Vladimir Vitalievich Gritsenko, Vladislav Nikolaevich Obolentsev, Dmitrii Yurievich Bukhan, Aleksei Eduardovich Maevskii, Hongchen Yu, Kun Gu, Jie Chen, Shiyao Xiao, Man Zhao, Jun Chen, Yunlong Li

Patent number: 7605444Abstract: Provided are a fuse box that simultaneously prevents damage caused by laser blowing and cross talk between the fuses and a method of manufacturing the same. In a fuse box having an open region in which fuses are opened by laser blowing and a bundle region in which fuse opens do not occur, a capping layer, adjacent to the open region, having a metal layer and an insulation layer covers the outermost fuses in the bundle region, thereby reducing the influence of laser blowing of fuses in the bundle region, and preventing capacitive coupling caused by the formation of a parasitic capacitor between fuse lines and an insulation layer therebetween. Accordingly, cross talk due to the capacitive coupling can be prevented, thereby enhancing the reliability of a fuse circuit. Lower fuses can be disposed in a lower layer in the bundle region, thereby forming a two-layered fuse box.Type: GrantFiled: December 13, 2006Date of Patent: October 20, 2009Assignee: Samsung Electronics Co., Ltd.Inventors: Kwang-kyu Bang, Kun-gu Lee, Jeong-kyu Kim
