Title:
抵抗変化型不揮発性記憶装置
Document Type and Number:
Japanese Patent JP5367198
Kind Code:
B1
Abstract:
Provided is a variable resistance element (Rij) the resistance state of which is reversibly changed by applying electrical signals of different polarities; and a current steering element (Dij) in which a first current is larger than a second current, the first current being a current which flows when a voltage of the first polarity having a first value is applied, the first value being less than a predetermined voltage value and having an absolute value greater than zero, the second current being a current which flows when a voltage of the second polarity having an absolute value which is the first value is applied, the second polarity being different from the first polarity, in which Rij and Dij are connected in series such that the polarity of a voltage to be applied to Dij is the second polarity when the resistance state of Rij is changed to high resistance state.
