Abstract
A word line driver includes an address decoder having a first circuit and a second circuit for selecting the word line, and a control end disposed between the first circuit and the second circuit. In addition, the word line driver has a level shift circuit for shifting a voltage level of the word line, and the level shift circuit has an input end connected to the second circuit of the address decoder. A method of driving a word line includes shifting a voltage level of the control end while turning on the second circuit so as to shift a voltage level of the input end of the level shift circuit, and shifting a voltage level of at least one of the first and second power supplies and using the second circuit to isolate the voltage level of the control end from the voltage level of the word line.
