Word line voltage regulation circuit

摘要

A word line voltage regulation circuit includes a first comparator for comparing a first reference voltage and the potential of an output node; a first switching element for supplying the supply voltage to the output node depending on the output signal of the first comparator; a second comparator for comparing a second reference voltage and the potential of the output node; a second switching element for regulating the potential of the output node depending on the output signal of the second comparator; a third switching element for transmitting the potential of the output node to a decoder circuit depending on a first control signal; and a fourth switching element for supplying the supply voltage to the decoder circuit depending on a second control signal.
