Abstract
A flip-flop circuit includes a data input terminal, a data output terminal, a memory circuit and a bypass circuit having a shorter delay time than that of the memory circuit. The memory circuit and the bypass circuit are connected in parallel between the data input terminal and the data output terminal so that the data are outputted to the data output terminal through the bypass circuit when the data are written in the memory circuit. As a result, the delay time of the flip-flop circuit is shortened.
