Abstract:
A resistance change memory device includes memory cells including two transistors connected in parallel between a first node and a connecting node and a variable resistance element whose one end is connected to the connecting node. The first node of each memory cell and a second node, which is the other end of the variable resistance element of the memory cell, are connected to different bit lines. The first node of a one memory cell and the first node of another memory cell which is adjacent on a first side along the second axis to the one memory are connected to the same bit line. The second node of the one memory cell and the second node of still another memory cell which is adjacent on a second side along the second axis to the one memory cell are connected to the same bit line.
