A packet switch capable of receiving fixed size data cells from N input ports and transmitting the fixed size data cells to N output ports. The packet switch comprises: 1) a frame deserializer for receiving the data cells as serial bits from the N input ports and transmitting the data cells as parallel bits in data frames containing a plurality of data cells, wherein each of the plurality of data cells in each data frame are destined for a common output port; 2) a frame serializer for receiving the data frames and transmitting the plurality of data cells in the data frames as serial bits to the N output ports; and 3) a shared buffer coupling the frame deserializer and the frame serializer for receiving and buffering the data frames from the frame deserializer and transmitting the buffered data frames to the frame serializer.
