ABSTRACT:
A floating gate structure wherein the floating gate is a second level polysilicon layer that is substantially shielded from the substrate by a segmented, discontinuous first level word line. Coupling of the floating gate to the substrate for "writing" is accomplished by extending the floating gate between word line segments while electrical continuity of the word line is maintained by buried contacts which make electrical contact to a continuous third level polysilicon layer.
