Abstract
A PCIe capable semiconductor device includes; ports respectively configured to transmit and receive data in a PCIe environment, and a PCIe controller configured to set a link between the PCIe capable semiconductor device and another PCIe capable semiconductor device. The link includes at least one lane implemented over at least one of the ports. The PCIe controller includes a link training and status state machine (LTSSM) configured to perform a first lane number negotiation according to a first ordering of the ports and a second lane number negotiation according to a second ordering of the ports different from the first ordering of the ports, and determine an optimized link width for the link according to the results of the first lane number negotiation and the second lane number negotiation.
