REF <They must have seen some very impressive performance gains>

If all the conclusions are being drawn from a simple memory device, AMD could be in for some surprises.

Memory device performance is more dominated by junction capacitance, so SOI will indeed shine. Logic devices performance is dominated by metal capacitance and not junction capacitance. So Logic devices badly need low-K dielectrics and do not benefit from SOI that much.

The floating substrate problems will be easier to model with the memory device. Complex microprocessors will be a lot harder to simulate.

The SOI gamble would be a lot safer if AMD was in the SRAM business. Hopefully for AMD's sake, they have evaluated a K-7 on SOI.
