STORAGE DEVICE DRIVE METHOD |
摘要 |
Provided is a method of driving a storage device capable of improving reliability of data write in the storage device including a variable resistance element. At the time of data write operation, a plurality of write pulses having shapes different from each other are applied between electrodes 21 and 24 in a variable resistance element 2. Diffusion loss of a conductive path caused by self-heat generation (generation of Joule heat) of the variable resistance element 2 may be prevented, and thus data hold operation after write is stabilized. Also, the variable resistance element 2 may be prevented from being destructed when the write operation is sufficiently performed, and thus the data write operation is stabilized.
