ABSTRACT:
Provided is a semiconductor memory device including an internal power supply with low current consumption, which includes: an active interval security block for generating active interval security signals with operation intervals by a row active signal and a column active signal; an active driving signal generating block for generating an active driving signal, responsive to the active interval security signals; a standby driving block for holding the level of an internal voltage; and an active driving block, which is additionally driven based on the active driving signal to hold the internal voltage.
