  • Patent number: 7265376
    Abstract: A nonvolatile memory cell, memory cell arrangement, and method for production of a nonvolatile memory cell is disclosed. The nonvolatile memory cell includes a vertical field-effect transistor (FET). The FET contains a nanoelement arranged as a channel region and an electrically insulating layer. The electrically insulating layer at least partially surrounds the nanoelement and acts as a charge storage layer and as a gate-insulating layer. The electrically insulating layer is arranged such that electrical charge carriers may be selectively introduced into or removed from the electrically insulating layer and the electrical conductivity characteristics of the nanoelement may be influenced by the electrical charge carriers introduced into the electrically insulating layer.

  • Patent number: 7208794
    Abstract: Semiconductor memory having memory cells, each including first and second conductively-doped contact regions and a channel region arranged between the latter, formed in a web-like rib made of semiconductor material and arranged one behind the other in this sequence in the longitudinal direction of the rib. The rib has an essentially rectangular shape with an upper side of the rib and rib side faces lying opposite. A memory layer is configured for programming the memory cell, arranged on the upper side of the rib spaced apart by a first insulator layer, and projects in the normal direction of the one rib side face over one of the rib side faces so that the one rib side face and the upper side of the rib form an edge for injecting charge carriers from the channel region into the memory layer.
