ABSTRACT:
Disclosed herein is an internal voltage generation circuit of a semiconductor memory device which is capable of supplying voltages of different levels to a column path & control logic and data path & control logic in the memory device according to different operation modes of the memory device. The column path & control logic and data path & control logic are applied with a normal operating voltage when they are involved in the current operation mode of the memory device, whereas with a lower voltage when they are not involved. Therefore, the present invention has the effect of efficiently managing internal voltages of the semiconductor memory device and reducing current leakage of the memory device and, in turn, unnecessary power consumption thereof.
