Abstract
A semiconductor storage device includes first signal lines divided into groups respectively including m (m is an integer equal to or larger than 2) of the first signal lines; and second signal lines. A memory cell array includes memory cells provided to correspond to respective intersections of the first signal lines and the second signal lines. A selection voltage is applied to any of the first signal lines through m global signal lines. First transistors are provided to respectively correspond to the first signal lines and connected between the first signal lines and the global signal lines. First selection signal lines are provided to respectively correspond to the groups and connected to gate electrodes of the first transistors included in a corresponding one of the groups in common. First dummy signal lines are arranged between adjacent ones of the groups, to which a non-selection voltage is applied.
