Abstract
A row decoder includes a logic decoder, a word line driver circuit, and first and second coupling circuits. The logic decoder provides a logic high in an inactive cycle and when selected in an active cycle, and a logic low when deselected in the active cycle. Each of a plurality of word line driver circuits receive a decoded address signal which corresponds to that particular driver circuit, each have an output coupled to a corresponding word line, and each have an input which, when at a logic high, causes that word line driver to couple its corresponding decoded address signal to its corresponding word line. The first coupling circuit couples the output of the logic decoder to the input of only the driver circuit which corresponds to an active decoded address signal during the active cycle, and for coupling the output of the logic decoder to all of the driver circuits in the inactive cycle. The second coupling circuit couples the word line which corresponds to the active decoded signal to the output of the logic decoder when the logic decoder is deselected during the active cycle.
