Abstract
A method of forming a memory device including a plurality of upwardly extending fins in a semiconductor substrate upper surface. A memory cell is formed on a first fin, and includes spaced apart source and drain regions in the first fin, with a channel region extending along top and opposing side surfaces of the first fin between the source and drain regions. A floating gate extends along a first portion of the channel region. A select gate extends along a second portion of the channel region. A control gate extends along the floating gate. An erase gate extends along the source region. A second fin has a length that extends in a first direction which is perpendicular to a second direction in which a length of the first fin extends. The source region is formed in the first fin at an intersection of the first and second fins.
