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.
