ABSTRACT:
A semiconductor memory device stably operates over a wide range of the power supply voltage by including a power supply voltage level detector for generating detecting signals according to predetermined levels of the power supply voltage and an oscillator for generating a frequency-controlled oscillation pulse whose frequency is changeable according to the detecting signals. Thus, a boosting ratio of a boosting circuit, the refresh period of a refresh circuit and the substrate voltage of a substrate voltage generator can be adaptively changeable according to the variation of the power supply voltage.
