Abstract
A resistive memory storage apparatus including a memory cell, a selecting transistor and a memory controller is provided. The memory cell outputs a writing current during a writing pulse width period. The selecting transistor is coupled to the memory cell. The memory controller is coupled to the selecting transistor and the memory cell. The memory controller is configured to apply a control voltage that gradually changes to a predetermined voltage level to a control end of the selecting transistor during a resistance transition phase of the writing pulse width period and set the control voltage to the predetermined voltage level during a filament stabilization phase after the resistance transition phase, so as to limit the writing current to a predetermined current value. In addition, an operating method for a resistive memory storage apparatus is also provided.
