Abstract
According to one embodiment, a resistance-change memory includes bit lines running in a first direction, word lines running in a second direction, and a memory cell array includes memory cells each includes a selection transistor and a variable resistance element. In a layout of first to fourth variable resistance elements arranged in order in the first direction, the first variable resistance element and the second variable resistance element sandwich one word line therebetween, the third variable resistance element and the fourth variable resistance element sandwich one word line therebetween, a first pair includes the first and second variable resistance elements and a second pair includes the third and fourth variable resistance elements sandwich two word lines therebetween, and a column is constructed by repeating the layout in the first direction.
