Programmable interface for single and multiple host use

摘要

A serial interface including a controller, a first unit interface, and a second unit interface. The first unit interface communicatively couples the controller with a host, wherein the first unit interface communicates with the host through a first set of lanes. The second unit interface communicatively couples the controller with the host, wherein the second unit interface communicates with the host through a second set of lanes, wherein the controller bonds the first unit interface and the second unit interface to function as a single entity for communicating with the host.
