Abstract
A data buffering storage circuit automatically allocates a portion of shared storage area to the direction in which data buffering is required. This scheme allows use of fewer parts on a piece of networking hardware, which in turn lowers the cost, simplifies the design, and uses existing on-board memory in a more efficient manner. In at least one embodiment, a first area is allocated to the buffering of a first port of a network switch, a second memory area is allocated to the buffering of a second port of the network switch, and a third area is shared among the buffering of the first port and the buffering of the second port.
