Abstract:
A word line voltage regulation circuit having a supply voltage, the word line voltage regulation circuit comprising:a first comparator for comparing a first reference voltage with potential of an output node, and outputting a first comparator output in response thereto; a first switching element for supplying the supply voltage to said output node depending on said first comparator output; a second comparator for comparing a second reference voltage with the potential of said output node, and outputting a second comparator output in response thereto; a second switching element for regulating the potential of said output node depending on the said second comparator output; a third switching element for transmitting the potential of said output node to a decoder circuit depending on a first control signal; and a fourth switching element for supplying said supply voltage to said decoder circuit depending on a second control signal; wherein said first switching element is a PMOS transistor connected between the supply voltage and said output node.
