Abstract
A wordline driver for DRAM comprises a multiplexer, an inverter and a transistor switch. One end of the multiplexer is connected to a wordline charging voltage, and the other end is connected to an external voltage, wherein the external voltage is less than the wordline charging voltage, and initially the external voltage is outputted. The output end of the inverter is connected to the select line of the multiplexer, and the input end thereof is electrically connected to the output end of the multiplexer. One end of the transistor switch is connected to the input end of the inverter, and the other end thereof is connected to the word line.
