Abstract:
Word-line drivers, memories, and methods of operating word-line drivers are provided. A word-line driver coupled to an array of memory cells includes a decoder powered by a first power supply. The decoder is configured to decode an address to provide a plurality of word-line signals. The word-line driver also includes a plurality of output stages powered by a second power supply that is different than the first power supply. Each of the output stages includes a first transistor having a gate controlled by a first control signal and an inverter. The inverter is coupled between the first transistor and a ground and has an input coupled to the decoder to receive one of the word-line signals. The word-line driver also includes pull-down circuitry coupled between the gates of the first transistors and the ground and activated by a second control signal.
