A method of forming a memory cell includes forming a conductive floating gate over the substrate, forming a conductive control gate over the floating gate, forming a conductive erase gate laterally to one side of the floating gate and forming a conductive select gate laterally to an opposite side of the one side of the floating gate. After the forming of the floating and select gates, the method includes implanting a dopant into a portion of a channel region underneath the select gate using an implant process that injects the dopant at an angle with respect to a surface of the substrate that is less than ninety degrees and greater than zero degrees.
