R-S Flip Flops
RS-type NAND Flip Flop
A basic logical device for information storage is the flip-flop (abbr. FF). A flip-flop can stay in one of two logic states. To change this stage it needs a new input signal. Thus a flip-flop is a one bit memory. A flip-flop containing a 1 is said to be set, if it contains a 0 it is reset. There exist three basic types of flip-flops:
* Memory flip-flops have special inputs to be set …

…store the number 100101?
A.2 Since R-S FF is a one bit memory, Six R-S FFs are required to store the six integers, 100101.
Q.3 For an R-S FF to change output conditions, the inputs must be in what states?
A.3 In order to change the output conditions, the inputs must be in 1 and 0, or opposite states.
Q.4 How may R-S FFs be constructed?
A.4 R-S Flip Flops can be constructed By cross-coupling NAND or OR gates.
