In the present invention a nonvolatile memory array architecture can be realized by a fabrication process more compatible to an MOS logic fabrication process as compared with previous nonvolatile memory array architectures. Higher write and/or read speed is possible because of a lower bit line resistance....http://www.google.de/patents/US6469935?utm_source=gb-gplus-sharePatent US6469935 - Array architecture nonvolatile memory and its operation methods
