Circuit for detecting address signal transition
 A first device serves to sense a start of a transition of an address signal and to generate a transition start signal representative thereof. The first device has a first predetermined input switching voltage with respect to the address signal. A second device serves to sense an end of a transition of the address signal and to generate a transition end signal representative thereof. The second device has a second predetermined input switching voltage with respect to the address signal. The first and second predetermined input switching voltages are positively different from each other.
