Cascade of flip-flops sharing the same clock, in which the output of each flip-flop is connected to the input of the next flip-flop in the chain, resulting in a circuit that shifts by one position the bit array stored in it
A shift register is a type of digital circuit using a cascade of flip-flops where the output of one flip-flop is connected to the input of the next. They share a single clock signal, which causes the data stored in the system to shift from one location to the next. By connecting the last flip-flop back to the first, the data can cycle within the shifters for extended periods, and in this configura... Wikipedia
