Abstract
Disclosed is a semiconductor device that reduces the area of a transistor in a ReRAM. A plurality of memory cells differ from each other in the combination of bit line and plate line. The potential of plate line PLis a forming voltage. By contrast, the potentials of the other plate lines are +Vi. The potential of bit line BLis 0 V (ground potential). By contrast, the potentials of the other bit lines are +Vi. The potential of is +Vgf. By contrast, the potentials of the other word lines are +Vi.
