A floating-node memory device includes a metal-oxide-semiconductor (MOS) transistor including a first polysilicon gate, a source region, and a drain region in a first well region, a tunneling device including a second polysilicon gate in a second well region, and a metal-insulator-metal (MIM) capacitor including a conductive top plate and a bottom plate formed in a metal interconnect layer. The floating-node device includes a floating-node comprising the first polysilicon gate, the second polysilicon gate, and the conductive top plate of the MIM capacitor coupled together, a control node at the bottom plate of the MIM capacitor, an erase node in the second well region, a source node at the source region of the MOS transistor, and a drain node at the drain region of the MOS transistor.
