Split gate non-volatile flash memory cell having metal gates

A memory device including a silicon substrate having a planar upper surface in a memory cell area and an upwardly extending silicon fin in a logic device area. The silicon fin includes side surfaces extending up and terminating at a top surface. The logic device includes spaced apart source and drain regions with a channel region extending there between (along the top surface and the side surfaces), and a conductive logic gate disposed over the top surface and laterally adjacent to the side surfaces. The memory cell includes spaced apart source and drain regions with a second channel region extending there between, a conductive floating gate disposed over one portion of the second channel region, a conductive word line gate disposed over another portion of the second channel region, a conductive control gate disposed over the floating gate, and a conductive erase gate disposed over the source region.
