Abstract
A writing method for a resistive memory apparatus is provided. In the method, logic data is received, and a corresponding selection memory cell is selected. A logic level of the logic data is determined. When the logic data is at a first logic level, a RESET pulse is provided to the selection memory cell and then a SET pulse smaller than a reference write current and having a near-rectangular pulse width is provided to the selection memory cell during a writing period. When the logic data is at a second logic level, the RESET pulse is provided to the selection memory cell and then a SET pulse larger than the reference write current and having the near-rectangular pulse width is provided to the selection memory cell during the writing period.
