Abstract
A transfer gate is provided between an input terminal, receiving voltage Vh of the super Vcc level when a special operating mode is set, and an inverter and an n channel MOS transistor included in a super Vcc detection circuit of a DRAM. The transfer gate is rendered conductive only during a potential detection period during which signal WCBR attain an 'H' level. Therefore, a leakage current flowing from the input terminal through the n channel MOS transistor to a ground terminal can be minimized, thereby reducing a consumed current.
