The present invention provides a non-volatile memory cell, array and fabrication method. The memory cell comprises a substrate, a gate structure, a source region and a drain region, wherein the gate structure is formed on the substrate, the gate structure sequentially comprises a first gate dielectric layer, a first conductive layer, a second gate dielectric layer and a second conductive layer from bottom to top, the source region is formed in the substrate, the source region comprises an N-type heavily doped source region, the drain region is formed in the substrate, the drain region comprises an N-type doped drain region and a P-type heavily doped drain region formed in the N-type doped drain region. The non-volatile memory cell and array provided by the present invention have a band-to-band tunneling programming ability and reserve the advantage of high reading current of an N-channel at the same time.
