    • Roughly described, a memory includes first and second target memory cells in a plurality of electrically adjacent memory cells all sharing a word line. The two target memory cells are separated from each other by at least one additional memory cell, and first current path terminals of the target memory cells bracket second current path terminals of the target memory cells electrically along the word line. The two target memory cells are read by connecting the first current path terminals of the two target memory cells to ground, precharging the second current path terminals of the two target memory cells to respective precharged states, and while both second current path terminals are in their respective precharged states, initiating a sense operation to read both the first and second target memory cells substantially simultaneously.

    • An improved word line boost circuit suitable for use on integrated circuits such as flash memory devices includes a two step boosting circuit with a floating circuit node. A first circuit provides an initial boost of the output voltage from a precharged voltage. Part of the first circuit is floated, lessening a load on a second circuit. Then, the second circuit provides a second boost of the output voltage with increased power efficiency. A time delay separates the onset of the second boosting operation from the onset of the first boosting operation so as to define a two-step boost.
