ABSTRACT:
A trigger pulse generator generates trigger pulses synchronized with the rising edges and falling edges of an input signal and is used, for example, in a semiconductor memory device in order to shorten the access time. The trigger pulse generator according to the present invention comprises: an amplifier which outputs a non-inverted signal of the input signal and an inverted signal of the input signal; a pair of depletion-type MIS transistors whose drains or sources are connected to the non-inverting output terminal and to the inverting output terminal of the amplifier and whose gate electrodes are connected to the inverting output terminal and the non-inverting output terminal, respectively; and a gate circuit which is connected to the sources or drains of the pair of depletion-type MIS transistors and which outputs the trigger pulses.
