What is the difference between Low Vt and Native device? I think the only difference is that the Vth of Native device is lower than the low Vt device. Is there any only differences?
During the fabrication of a transistor there is a Threshold Adjust Implant that increases the Vt of the transistor (it is basically a small doped region at the interface between the substrate and the oxide). The Vt is adjusted by playing with this implant, originating several devices with different Vt's, in the same technology.
Native devices do not have this implant. As far as I know this is the main difference.
