A three-dimensional (3-D) module with integrated passive components includes a plurality of vertically stacked sub-modules. Each sub-module comprises a device level comprising a high-k dielectric (e.g. ceramic) material and an interconnect level comprising a low-k dielectric (e.g. organic) material. The passive components in the device level are fired integrally, whereas the device level and the interconnect level are fired independently.

The present invention discloses a multi-bit-per-cell three-dimensional resistive random-access memory (3D-RRAM). It comprises a plurality of RRAM cells stacked above a semiconductor substrate. Each RRAM cell comprises a RRAM layer, which is switched from a high-resistance state to a low-resistance state during programming. By adjusting the programming current, the programmed RRAMs have different resistances.
