Abstract
A resistance change type memory includes a variable resistance element connected between first and second bit lines and a write control circuit including first and second transistors each including a terminal connected to the first bit line. The write control circuit controls write to the variable resistance element. The write control circuit supplies a second voltage to the first bit line with a first pulse width via the second transistor in the ON state after supplying a first voltage to the first bit line via the first transistor.
