Abstract
An address memory structure used in an Ethernet switch, comprising an index memory and an address table memory is disclosed. The index memory is used for storing the vendor code section and the address table memory is used for storing the serial code section. The vendor code index data connects the index memory data to the address table memory data. When comparing the node addresses, the serial code section in the address table memory is compared first. If there is a consistent entry, the corresponding vendor code section is compared through the vendor code index data. When adding a new node address, the corresponding vendor code index data is attained, and the vendor code index data and the serial code of the node address are then written into the address table memory.
