Disclosed is a resistive random access memory (RRAM). The RRAM includes a bottom electrode made of tungsten and a switching layer made of hafnium oxide disposed above the bottom electrode, wherein the switching layer includes a switchable filament. The RRAM further includes a resistive layer disposed above the switching layer and a bit line disposed above the resistive layer, wherein the resistive layer extends laterally to connect two or more memory cells along the bit line.
