The outputs of a combinational circuit depend on the inputs at the time of measurement. In other words, a combination of logic values at the inputs will determine the logic values at the outputs after the circuit becomes stable.

In information technology when storage comes into the picture, we always think of the databases. Apart from that, the concept of latches and flip-flops are widely used to store data as bit Contamination Delay вЂў The contamination delay, t cd, is the minimum time from when an input changes until any output changes (not necessarily going to the steady value).

In electronics, a flip-flop or latch is a circuit that has two stable states and can be used to store state information вЂ“ a bistable multivibrator.The circuit can be made to change state by signals applied to one or more control inputs and will have one or two outputs. It is the basic storage element in sequential logic.Flip-flops and latches are fundamental building blocks of digital Digital Memory: Latches and Flip-Flops CPSC 2105 Revised 5/14/2013 Page 2 of 32 Requirements for a Digital Memory Cell Each digital memory cell is a memory device that stores a single bit: 0 or 1. In most common memory cells, the bits are stored as electronic voltages.

Latches and Flip-Flops вЂў A flip-flop samples its inputs and changes its inputs only at times determined by a clocking signal. вЂў A latch watches all of its inputs continuously and changes its outputs at any time, independent of a clocking signal.

Flip-flops and latches вЂў Flip-flops and latches are the fundamental elements of sequential circuits вЂ“ bistable (two stable states) вЂў Flip-flops and latches are essentially 1-bit storage devices вЂ“ outputs can be set to store either 1 or 0 depending on the inputs вЂ“ even when the inputs are deasserted, the outputs retain their prescribed Both latches and flip-flops are circuit elements whose output depends not only on the current inputs, but also on previous inputs and outputs. The difference between a latch and a flip-flop is that a latch does not have a clock signal, whereas a flip-flop always does. Latches

Chapter 7 вЂ“ Latches and Flip-Flops Page 3 of 18 a 0. When both inputs are de-asserted, the SR latch maintains its previous state. Previous to t1, Q has the value 1, so at t1, Q remains at a 1. Similarly, previous to t3, Q has the value 0, so at t3, Q remains at a 0. If both S' and R' are asserted, then both Q and Q' are equal to 1 as shown at time t4.If one of the input signals is Latches and flip flops are the basic elements and these are used to store information. One flip flop and latch can store one bit of data. The main difference between the latches and flip flops is that, a latch checks input continuously and changes the output whenever there is a change in input. But, flip flop is a combination of latch and clock that continuously checks input and changes the
