An optical amplifier system and method are disclosed for amplifying CWDM channels. The memory hub controller is coupled to the memory hub through a first portion of a memory bus on which the memory requests from the memory hub controller and memory responses from the memory hub are coupled. The stent is self-expanding or uses a balloon to expand the stent in the heart wall. The said second stripe size is different than said first stripe size. Next, a second interlayer dielectric film is deposited on the first interlayer dielectric film so that the gaps between the gates are completely filled.
