A method and system for controlling a boosted wordline voltage that is used during a read operation in a flash memory is disclosed by the present invention. In the preferred embodiment, a gate voltage is generated by a voltage booster in a wordline voltage booster circuit. An adjustable clamp circuit is electrically connected with the wordline voltage booster circuit for clamping the gate voltage that is generated by the voltage booster at a predetermined voltage level. The predetermined voltage level may be adjusted with a trimming circuit that is electrically connected to the adjustable clamp circuit, depending on process variations experienced during fabrication by the adjustable clamp circuit. |
