Abstract
An operating method of a resistive memory storage apparatus includes: applying a forming voltage to a memory cell and obtaining a cell current of the memory cell; and determining whether to adjust the forming voltage and apply the adjusted forming voltage to the memory cell according to a magnitude relationship between the cell current and a reference current. The memory cell to which the forming voltage is applied operates in a heavy forming mode and serves as a one-time programmable memory device.
