Web17 feb. 2024 · Bit-Flip: The Name Tells The Story Digital data is stored as a sequence of 0s and 1s. Each 0 or 1 is called a bit. A bit-flip is an inadvertent change of state of a bit that is different from its initial state. For example, if a bit changes from 0 to 1 or vice-versa accidentally, the event is called a bit-flip. WebSimilarly, when a flip-flop is set its value is taken as 1 and when it is reset its value becomes 0. One flip-flop represents one bit of memory.
