Can't say for sure, as >I do not recall the analysis exactly. I wasn't able to find anything about that. I didn't try that hard, however. If you can find a reference, it would be nice. As the following link shows, MultiValued Logic (MVL) is not only an active area of research, it is possible to have it used in a computer anyone can buy. It says that 4-valued logic is being used in some of the higher capacity DRAMs: http://web.it.kth.se/~elena/PAPERS/NORCHIP99b.pdf > >It should be easy enough to create base 3 circuits, since you would have +, 0 >and - as natural states.
