Abstract
A power-source controller for reducing current consumption while a DRAM is in standby, includes a mode detection circuit inverting a disable signal having an L-level under the enable state and having an H-level under the disable state; an internal-power-source driver circuit having first and second transistors; and an internal-power-source reference circuit setting first and second driver control signals respectively to L-level and H-level when an L-level disable signal is input to turn on the first transistor and turn off the second transistor, supplying an external-power-source voltage as an internal-power-source voltage, setting the first driver control signal to H-level when an H-level disable signal is input, controlling the level of the second driver control signal to turn off the second transistor and control the first transistor, and supplying an internal power-source voltage lower than the external-power-source voltage.
