Abstract
A dual power rail word line driver for driving a word line of a memory array according to a predecode signal from a decoder powered by a first supply voltage is provided. A signal buffering unit is coupled between the word line and a node. A pull-down unit is coupled between the node and a ground. A pull-up unit is coupled between the node and a second supply voltage higher than or equal to the first supply voltage. The signal buffering unit provides a word line signal corresponding to the predecode signal to the memory array via the word line when the pull-down unit is turned on by the predecode signal and a first pulse signal and the pull-up unit is turned off by a second pulse signal. There is no level shifter on a critical timing path of the dual power rail word line driver.
