Abstract
A semiconductor device according to the invention is composed of a counter which outputs intermediate carry signals (CARRY 0, 1, 2) and the final carry signal (CARRY END) for determining the end of a delay output signal in a period starting from a delay pulse-generating trigger signal (DPT) and continuing for a predetermined time, and a delay circuit which outputs count up signals (COUNT UP) for counting up the counter on the basis of pulse signals generated in accordance with the intermediate carry signals and the DPT. According to the aforementioned semiconductor device, the delay output signal can be outputted without using an external clock signal.
