Patent ID: 8711601

Claim:
A resistive random access memory module (RRAM module) electrically coupled to a RESET voltage, the RRAM module comprising: a switch electrically coupled to the RESET voltage; and a resistive random access memory cell (RRAM cell) comprising a first electrode, a second electrode, and a plurality of repeated sets of layers, each of the sets of layers comprising a resistance-changing layer, a barrier layer, and an ionic exchange layer between the resistance-changing layer and the barrier layer, where the thickness of each of the resistance-changing layer, the barrier layer and the ionic exchange layer exceeds a Fermi wavelength, and the thickness of the resistance-changing layer and the ionic exchange layer are each less than an electron mean free path, the first electrode being electrically coupled to the switch, wherein a resistance of the repeated sets of layers of the RRAM cell is R 1 , a resistance of the switch is R 2 , and 3≦R 1 /R 2 during RESET operation.
