  • Patent number: 11902087
    Abstract: In a forwarding fault location determining method, a controller receives a plurality of table search statistical results of a plurality of forwarding tables for a first service from one or more forwarders. The plurality of forwarding tables include a first forwarding table and a second forwarding table, and the first forwarding table is prior to the second forwarding table in terms of a search sequence. Subsequently, the controller determines that table search behavior of the first forwarding table for the first service is normal and table search behavior of the second forwarding table for the first service is abnormal. The controller determines, based on the determining result, that the second forwarding table is a faulty forwarding table for the first service.

  • Patent number: 11444163
    Abstract: Embodiments of memory devices and fabrication methods thereof are disclosed. In an example, a memory device includes a substrate, a memory stack, and a channel structure. The memory stack includes interleaved conductor layers and dielectric layers over the substrate. The channel structure extends through the memory stack into the substrate and includes a functional layer that includes a tunneling layer of which a nitrogen weight percent is not greater than about 28%.

  • Patent number: 10167203
    Abstract: A method for preparing a suspension of LDH particles comprising the steps of: preparing LDH precipitates by coprecipitation to form a mixture of LDH precipitates and solution; separating the LDH precipitates from the solution; washing the LDH precipitates to remove residual ions; mixing the LDH precipitates with water; and subjecting the mixture of LDH particles and water to a hydrothermal treatment step by heating to a temperature of from greater than 80° C. to 150° C. for a period of about 1 hour to about 144 hours to form a well dispersed suspension of LDH particles in water, wherein said LDH particles in suspension comprise platelets having a maximum particle dimension of up to 400 nm.
