Abstract
A semiconductor device which enables quick and reliable adjustment of the address transition detection pulse width has an address transition detector (ATD) and n PMOS transistors connected in parallel to an output terminal, the PMOS transistors behaving as pull-up transistors for the ATD. The PMOS transistors are controlled by controlling outputs of n controllers which generate the outputs from a pulse-like waveform applied to an input terminal thereof, thus the size of the PMOS transistors are substantially changed.
