Abstract:
1. A wordline driver applied in a dynamic random access memory (DRAM), comprising: a first transistor comprising a first terminal for receiving a first voltage and a second terminal for outputting the first voltage, wherein the first transistor selectively provides the first voltage to a wordline; a second transistor comprising a third terminal for receiving a second voltage and a fourth terminal for outputting the second voltage, wherein the fourth terminal is electrically connected to the second terminal of the first transistor, the second transistor provides the second voltage to the wordline, and the second voltage is used to enable the wordline; and an inverter, one end of the inverter electrically connected to a gate of the first transistor to control the first transistor to selectively provide the first voltage to the wordline, and the other end of the inverter electrically connected to the fourth terminal of the second transistor.
