A non-volatile memory having a plurality of memory units is provided. Each memory unit includes a first memory cell and a second memory cell. The first memory cell is disposed on the substrate. The second memory cell is disposed on one sidewall of the first memory cell and the substrate. The first memory cell includes a first control gate disposed on the substrate and a composite layer disposed between the first control gate and the substrate. The second memory cell includes a pair of floating gates disposed on the substrate, a second control gate disposed on the upper surface of the two floating gates, an inter-gate dielectric layer disposed between the floating gate and the second control gate, a tunneling dielectric layer disposed between the floating gate and the substrate and a gate dielectric layer disposed between the bottom of the second control gate and the substrate.
