One embodiment of the present invention provides a switch in a network of interconnected switches. The switch includes a storage device, a hardware management apparatus, and a layer-2 management apparatus. The storage device stores a forwarding table, which includes an entry comprising a MAC address and an egress port for the MAC address. The hardware management apparatus determines whether a destination MAC address of a frame is present in a hardware table in memory of the switch. The layer-2 management apparatus, in response to a determination that the destination MAC address is not present in the hardware table, looks up a first entry comprising the destination MAC address in the forwarding table, and creates a second entry comprising the destination MAC address in the hardware table based on the first entry.

Via definition for semiconductor die

Номер: US8288814B2
Автор: Chetan Verma, Pankaj K Jha, Rajesh Bansal
Принадлежит: FREESCALE SEMICONDUCTOR INC

A semiconductor die includes a first set of metal lines and a second set of metal lines. The first set of metal lines and the second set of metal lines are placed in alternate planes and are orthogonal to each other. A via is used to connect a first metal line from the first set of metal lines with a second metal line from the second set of metal lines. The via location is offset such that a side of the first metal line is aligned with a side of the second metal line. Consequently, a metal line adjacent to the first metal line does not need to detour around the via.
