Abstract
In an address transition detecting circuit, signal conversion detecting circuits output complementary time difference signals which are inverted in response to potential level changes of corresponding address lines respectively. Waveform shaping one-shot pulse generating circuits receive corresponding complementary time difference signals and output one-shot pulse signals of prescribed time widths. A waveform composing circuit outputs an ATD signal of a prescribed pulse length in response to activation of any one-shot pulse signal. Therefore, the lengths of the one-shot pulses outputted from the waveform shaping one-shot pulse generating circuits remain unchanged even if the potential level of any signal line is abruptly converted, and an ATD signal of a constant pulse length is regularly outputted.
