What are Flip Flops...Electronic Flip Flops to be exact...?

A. Stupid sandle like shoes that hardly stay on your feet.


B. Somthin that a fish does when it comes onto land. lol


or


C. XOR, OR, AND, NOT.





Please tell me what you know about flip flops.





Is it true that there are two ______ per Flip Flop, or what.





I am very interested in Computers, and Technology in general.





Tell Me What You Know, Please.





Thank You.

What are Flip Flops...Electronic Flip Flops to be exact...?
flip flops (also known as latches) are basic building block of memory circuits. They are 2 nand gates (SR FF) that make a flip flop and the outputs of each nand gate are looped back onto the other%26#039;s input. (2 transistor answer is incorrect. NAND gates are made with transistors:micro electronics)





There are different types of flip flops and you can read about them. Memory today uses capacitors (which is why you see refreshrates for RAM modules today), however FFs were used in the beginning. In some circuits FFs are still used.





Internally, FFs have an inherent problem of a quasi stable state. If you analyze a FF under a logic analyzer, you can see that it takes some time for the output pins to settle to a binary 1 or 0. This quasi stable state introduces a performance (or timing) problems as well as some electrical problems when lots of them are used.





Performance wise, nand gates are faster than the others. It just happens to be that way because the underlying transistor network is simpler.








You can make any combination logic circuit with a an infinite amount of XOR gates. If you can prove this by yourself, you%26#039;ll be awesome at this.





If you want to learn more, you can read about it in wiki (history) or you can learn computer engineering etc at MITs opencouseware





I hope this helps





btw I love these questions.
Reply:A Flip flop is an electronic circuit which has two stable states - 1 and 0. It is made by having gates(not Bipolar Junction transistors) combined in a circuit. So, your output from the circuit will either be 1 or 0 . In most cases it will contain two outputs, Q , and its complement. So if one is 1, other will be 0.
