Abstract
Disclosed is an operating method of an electronic device which includes a semiconductor memory having a plurality of resistive storage cells. The operating method may include: writing data to the resistive storage cells using a write current of a set condition; determining whether the writing of data to the resistive storage cells is successful, wherein the writing of data is determined to be failed when the number of resistive storage cells with failed writing of data exceeds a reference value, and successful when the number of resistive storage cells with failed writing of data is equal to or less than the reference value; strengthening the set condition when the writing of data is determined to be failed; and easing the set condition when the writing of data is determined to be successful.
