What is a Flip-Flop?

A flip-flop is a digital memory circuit that stores one bit of data. They are the primary blocks of the most sequential circuits. It is also called one-bit memory, binary, or a bistable multivibrator. Flip-flops act as memory elements in a sequential circuit. You can obtain the output in the sequential circuits using a flip-flop, a combinational circuit, or both.

A flip-flop state repeatedly changes at an active state of the clock pulses. They remain unaffected even when the clock pulse does not stay active. The clocked flip-flops particularly act as the memory elements of the synchronous sequential circuit- while the un-clocked ones (latches) function as the memory elements of asynchronous sequential circuits.

There are mainly four types of flip-flops:

• JK Flip-Flop

• SR (Set-Reset) Flip-Flop

• Data or Delay (D) Flip-Flop

• Toggle (T) Flip-Flop

What Is a Latch?

A latch is an electronic device that changes its output immediately on the basis of the applied input. One can use it to store either 0 or 1 at a specified time. A latch contains two inputs- SET and RESET, and it also has two outputs. They complement each other. One can use a latch for storing one bit of data. It is a memory device- just like the flip-flop. But it is not synchronous, and it does not work on the edges of the clock like the flip-flop.
