The trick is to put a D-type flip-flop on the input data path, as shown in Figure 2. Now the problem is solved. In this case, the MC100EP29DT from ON Semiconductor synchronizes the parallel input ...

Rather, the nonvolatile magnetic flip flop demonstration proves that handhelds of the future could eventually be made to boot up faster and retain data even when completely powered off.

By the mid-20th century, the flip-flop was a breakthrough in circuit logic, which allowed data to be stored. The first flip-flops, known as "trigger circuits," were constructed with two transistors.
