Abstract
A boost level clamping circuit and a method for clamping a boosted wordline voltage from a booster circuit used in a semiconductor memory device is provided which is power supply and process corner independent. The clamping circuit is formed of a plurality of parallel-connected clamp stages connected to the boosted wordline voltage from the booster circuit. Each of the plurality of clamp stages serves to clamp the boosted wordline voltage at different predetermined levels. Each of the clamp stages is formed of a sampling circuit, a comparator circuit, a pulse generator circuit, and a pull-down circuit.
