Abstract:
1. A semiconductor storage device comprising: a first selection line; a second selection line that crosses the first selection line; a first memory cell chain which is connected to the first selection line substantially at a crossing of the first selection line and the second selection line and in which a first memory cell and a second memory cell are serially connected; and a first diode which is connected between the second selection line and the first memory cell chain substantially at the crossing of the first selection line and the second selection line, wherein a first variable resistance element and a first memory selection switch which controls current applied to the first variable resistance element are electrically and parallelly connected in the first memory cell; and a second variable resistance element and a second memory selection switch which controls current applied to the second variable resistance element are electrically and parallelly connected in the second memory cell.
