Patent number: 8457143Abstract: A lossless handover method in vehicular wireless networks is disclosed which is capable of reducing a handover delay and reducing overhead caused by duplicate address detection (DAD) for a new Care-of-Address (CoA) by dividing a handover process into handover at road-sections and handover at intersections. In the handover method, a vehicle continues to use an original CoA configured at an original access router at road-sections even though an AR is changed, thereby reducing a handover delay. A new CoA is configured only at intersections to reduce a binding update time of a home agent which is remotely present in an external network at road-sections. When performing the DAD for a new CoA at intersections, since the vehicle performs the DAD as a background process while performing communication using an original CoA, overhead caused by the DAD can be reduced.Type: GrantFiled: September 18, 2009Date of Patent: June 4, 2013Assignee: Seoul National University Industry FoundationInventors: Ha Young Oh, Chong Kwon Kim

Patent number: 8394698Abstract: A NAND flash memory array, an operating method and a fabricating method of the same are provided. The NAND flash memory array has a cut-off gate line under a control gate in order to operate two cells having vertical channels independently with one control gate (i.e., a shared word line). The memory cell area is reduced considerably compared to the conventional vertical channel structure, and is better for high integration. A shared cut-off gate turn off is made during a programming operation and prevents programming the opposite cell by a self-boosting effect. It is possible to shield electrically with a shared word line (a control gate) during a reading operation, and minimizes the effect of storage condition of the opposite cell. Also, the NAND flash memory array can be fabricated by using the conventional CMOS process.Type: GrantFiled: June 28, 2011Date of Patent: March 12, 2013Assignee: Seoul National University Industry FoundationInventors: Byung-Gook Park, Seong Jae Cho
