  • G11C 2216/04 Nonvolatile memory cell provided with a separate control gate for erasing the cells, i.e. erase gate, independent of the normal read control gate
  • G11C 2216/06 Floating gate cells in which the floating gate consists of multiple isolated silicon islands, e.g. nanocrystals
  • G11C 2216/08 Nonvolatile memory wherein data storage is accomplished by storing relatively few electrons in the storage layer, i.e. single electron memory
  • G11C 2216/10 Floating gate memory cells with a single polysilicon layer
