Hey guys,
I was thinking of a new concept whereby we could
square the amount of information stored in a bit. Currently, the
information stored in a bit is whether the bit is on or off. To put it
simply, the information has a base (remember, logarithmic base) of 2.
If we could develop a mechanism whereby the base can be increased to 3
or 4, the amount of information stored can increased to more than
1.584 times in the case where the base is increased to two or 2
(twice ) if the base is increased to 4.
This can be accomplished by sensitizing 3(4 if
possible) voltage levels instead of the two currently. Your comments
are invited.

I do it all the time, but not at speed... I use it to set options on a
chip:
Option 1, pin grounded
Option 2, pin floating
Option 3, pin tied to VDD
