Abstract: Disclosed herein are a PCI Express switch and a computer system using the switch, which do not require a separate switch device for communication between computers, and enable a switch to be mounted in each PCI Express (PCIe) device, thus enabling main memory to be shared between the computers. The PCI Express switch is employed in a computer system, and includes a downstream port for transmitting a packet, and an upstream port for receiving the packet, wherein the downstream port and the upstream port are directly connected to another computer system. The present invention has a structure which enables the memory of other computers to be accessed by changing only the structure of a switch within a computer. Accordingly, there is an advantage in that the memory of other computers can be directly accessed without requiring a separate switch device or complicated software for a connection between computers.
