Abstract
A memory includes first-lines, second-lines, and memory cells. Third-lines are provided to respectively correspond to groups each comprising m (m≥2) lines of the first-lines. A first selector selects a certain one of the first-lines from the groups and to connect the selected first-lines to the third-lines corresponding to the groups. Fourth-lines correspond to the third-lines. A second selector selects one of the third-lines and to connect the fourth-line to the selected third-line. A third selector selects a certain one of the second-lines. A first driver applied a voltage to the fourth-line. A second driver is connected to the third selector. The first driver charges the third-line corresponding to the first-line selected from the groups via the fourth-line. The first and second selectors bring the selected first-line and the third-line corresponding the first-line to an electrically floating state. The second driver applies a voltage to the selected second-line.
