Claim:
1. A resistive random access memory (RRAM) device, comprising: a first control line; a second control line; a RRAM cell, coupled between the first control line and the second control line, having a programmable resistive element, wherein the programmable resistive element has a high resistance state and a low resistance state; a first programmable current source, for selectively providing a configuration current to the RRAM cell; and a first programmable voltage source, for selectively providing a configuration voltage to the RRAM cell; wherein a state of the programmable resistive element of the RRAM cell is configured according to the configuration current and the configuration voltage; and the programmable resistive element is configured to the low resistance state by setting the configuration current to be lower than a reset current threshold of the programmable resistive element and setting the configuration voltage to be higher than a set voltage threshold of the programmable resistive element.
