Bistable element

The most fundamental bistable element, the raw material from wuhich all flip flops are constructed, is a pair of inverters connected to each other. No matter whether the input to one of them is TRUE or FALSE, the circuit is always self consistent; yet the design is completely symmetric between the two alternatives.
