发明名称 High voltage wordline driver with a three stage level shifter
摘要 A method and system is disclosed for a wordline driver circuit used for a memory device. It has a logic stage operating between a ground voltage and a first supply voltage and generating a logic stage output signal swinging between the ground voltage and the first supply voltage. It also has a mid voltage stage, operating between a raised ground voltage and a second supply voltage during the programming process, and generating a mid voltage stage output that swings between the second supply voltage and the raised ground voltage. It then has a high voltage stage, operating between the raised ground voltage and a third supply voltage, and generating a wordline driver output swinging between the third supply voltage and the raised ground voltage based on the received mid voltage stage output.
