An RRAM structure includes a substrate. An RRAM is embedded in the substrate. The RRAM includes a bottom electrode, a metal oxide layer and a top electrode. A first doped region is embedded in the substrate and surrounds the bottom electrode. A transistor is disposed on the substrate and at one side of the RRAM. The transistor includes a gate structure on the substrate. A source is disposed in the substrate and at one side of the gate structure. A drain is disposed in the substrate and at another side of the gate structure. The first doped region contacts the drain.

RRAM structure and method of fabricating the same

An integrated circuit includes: a substrate having a resistive random-access memory area and a resistor area; a first dielectric layer and a second dielectric layer sequentially disposed on the substrate; a patterned stacked structure having a bottom conductive layer, an insulating layer and a top conductive layer stacked from bottom to top sandwiched by the first dielectric layer and the second dielectric layer; a first metal plug and a second metal plug disposed in the second dielectric layer and contacting the top conductive layer and the bottom conductive layer of the resistive random-access memory area respectively, thereby constituting a resistive random-access memory cell; and, a third metal plug and a fourth metal plug disposed in the second dielectric layer and contacting the bottom conductive layer or the top conductive layer of the resistor area, thereby constituting a resistor cell. A method of forming said integrated circuit is also provided.
