Title:
NON-VOLATILE STORAGE ELEMENT DRIVE METHOD AND INITIALIZATION METHOD AND NON-VOLATILE STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/108185
Kind Code:
A1
Abstract:
A non-volatile storage element drive method comprises: an initialization step of applying an initialization voltage pulse to a series circuit wherein a load resistor (5) having a first resistance value is connected in series to a resistance change element (9) in an initial state and an MSM diode (4), thereby reducing the resistance value of the resistance change element (9); a write step of applying a write voltage pulse to the series circuit after the initialization step upon setting the resistance value of the load resistor (5) to a second resistance value which is lower than the first resistance value; and an erase step of applying an erase voltage pulse to the series circuit after the initialization step upon setting the resistance value of the load resistor (5) to a third resistance value which is lower than the first resistance value.
