Abstract:
A resistance change type memory includes first, second and third drive lines, a resistance change element having one end connected to the third drive line, a first diode having an anode connected to the first drive line and a cathode connected to other end of the first resistance change element, a second diode having an anode connected to other end of the first resistance change element and a cathode connected to the second drive line, and a driver/sinker which supplies a write current to the resistance change element. A write control circuit is arranged such that when first data is written, the write current is caused to flow in a direction from the first drive line to the third drive line, and when second data is written, the write current is caused to flow in a direction from the third drive line to the second drive line.
