Temporary Properties of RS Fuzzy Flip – Flops

Abstract

The RS flip-flop is a basic element of the computer random access
memory. The same structure provides new properties by using fuzzy operations instead of Boolean ones. Applying probabilistic fuzzy operators, we have found that bi-stability of RS flip-flop is changed into monostability, i.e. the memory achieves the ability of spontaneous forgetting. When two fuzzy flip-flops are interconnected in a proper way, Hebbian learning occurs. This means that if inputs occur simultaneously, the outputs are turned up for much longer period, comparing to pulses which are not overlapped. This property can be applied to RS flip-flops grid network. In this case, the excitation of flip-flop outputs depends on input pulses (their magnitudes, durations and positions in the time scale) as well as on a connection topology of the grid.
