CONSTITUTION: A plurality of first word lines(245) are extended from one of first terminals to second terminals in a second direction and are finished between the first terminals and the second terminals. A first direction is vertical to the second direction. A plurality of second word lines are extended from one of the second terminals to the first terminals in a third direction and are finished in one end of the first word lines. Each word line is aligned with one of the first word lines. [Reference numerals] (200) Page buffer sensing circuit; (230) Sensing circuit;
