Abstract
A disclosed flip-flop includes primary and secondary sections connected to switchable and continuous power supplies, respectively. The primary section includes logic outputting first control signals, a primary latch controlled by the first control signals, and a data output device connected to an output terminal of the primary latch. The secondary section includes logic outputting second control signals and a secondary latch. A first transmission gate controlled by the second control signals is connected between the output terminal of the primary latch and an input terminal of the secondary latch. A second transmission gate controlled by the first and second control signals is connected between output and input terminals of the secondary latch. In a normal mode, both sections receive power and the first transmission gate is conductive. In a retention mode, the primary section is powered down, the first transmission gate is non-conductive and the second transmission gate is conductive.
