NONVOLATILE SEMICONDUCTOR STORAGE DEVICE AND METHOD FOR WRITING THRERIN

摘要

A nonvolatile semiconductor storage device is provided with a resistance storage element (10) for storing a high resistance state and a low resistance state; a voltage generating circuit (12) for generating a write voltage for writing the high resistance state in the resistance storage element (10); a current generating circuit (14) for generating a write current for writing the low resistance state in the low resistance storage element; and a control circuit (16) for applying a write voltage to the resistance storage element (10) at the time of writing the high resistance state in the low resistance element (10) and applying a write current to the low resistance storage element (10) at the time of writing the low resistance state in the low resistance storage element (10).
