Abstract
A method of operating an EPROM which has a word line, a predecode circuit having an ou tput terminal and a transistor having a first electrode connected to the output terminal of the predecode circuit, a second electrode connected to a word line and a control gate. The method of operating the EPROM includes generating a selection signal and an inverted signal thereof in accordance with an internal address signal, and generating a delayed signal responsive to the selection signal and the inverted signal so that the delayed signal rises by a predetermined time delay behind a rising of the selection signal and rapidly falls substantially simultaneously with a rising of the inverted signal. Thereafter the potential of the selection signal is boosted in accordance with a potential of the delayed signal and the boosted selection signal is supplied to the control gate of the transistor connected between the predecode circuit and the word line.
