Abstract: PURPOSE: A circuit for detecting address transition within a semiconductor memory device is provided to generates a pulse signal whose output speed is varied due to variation of applied voltage within low applied voltage, and to generates a pulse signal whose output speed is constant regardless of variation of applied voltage within high applied voltage. CONSTITUTION: A circuit for detecting address transition within a semiconductor memory device includes the first inverting circuit, the first node(Node 11), a precharge circuit, a delay circuit(10), a delay selection circuit(40) and a decoding circuit(ND11). The first inverting circuit inverts a sum signal(sum) of detection signals of address transition. Pulse width of the sum signal(sum) is increased and ouputted to the first node(Node 11). When the sum signal(sum) is inactivated, the precharge circuit precharges the first node(Node 11) into a level of applied voltage. In the first delay path, a delay signal whose pulse width is varied according to applied-voltage in a low voltage area. In the second delay path, a delay signal whose pulse width is constant regardless applied-voltage in a high voltage area. The delay selection circuit(40) selects one of the two delay paths according to a level detection signal(PLD) for the applied voltage. The decoding circuit(ND11) outputs a pulse signal(ATDout2) according to a delayed signal from the selected delay path.
