What is a bistable multivibrator circuit commonly named?

A circuit that has two stable states and can store a single bit of information is being described. Because it can “flip” between these two states and then hold whichever state it ends up in, this type of device is commonly called a flip-flop. The key idea is memory: the output maintains its state even after the input that changed it is removed, until a new input changes it again. This distinguishes it from simple logic gates like AND or OR, which don’t remember past inputs, and from a clock, which is just a timing signal. Flip-flops are the fundamental memory elements used to build registers and counters, with various forms such as SR, D, JK, and T flip-flops.
