What are memory flip flops?
Flip flops are the basic building block of a memory. Flip flops are staple devices of components that can be set to logic 0 or logic 1 by applying control signal at its inputBelow are some types of flip flops
Reset Set flip flops (Rs flip flops)
Rs flip flops has two stable states and it remains in one of their state until triggered to the other state. Flip flops function in such a way that
Each flip flops collector drives the opposite through 100k base ohms resistors
Flip flops transistor will be operated in circulation or cut of state for example if the right transistor is saturated its collector voltage is approximately 0 volts. This means that the base drive for the left transistor is zero volts and so it is a cut off and its collector voltage is +5V. This in turn means that flip flops collector voltage of the left transistor produces enough base circuit in the left transistor to sustain its saturation
The overflow circuit of flip flops is latched or cut with the left transistor saturated and the right transistor cut off
By similar argument if the right flip flops transistor is saturated then the left flip flop transistor would be cut off. The output Q can be below or high i.e. binary 0 or 1 if latched the flip flop circuit will be binary 1
NOR LATCHE FLIP FLOP
This flip flop is a discrete circuit like transistor latches and are rarely used because they are bulky and expensive, but edges NOR Rs latches can be build using NOR gate and NAND gates
Clocking Rs flip flops
This is the third type of flip flops transistor which computes using thousand of flip flops, to coordinate the overload action, a square wave signal called the clock is send to each flip flop this signal prevent the flip flop from changing state until at the right time
Data flip flop – D flip flop
This is a flip flop but within inputs connected through an inverter logic circuit. Data flip flop has one input terminal and output terminal. It has an Rs flip flop whose input terminal are connected through an inverter
