    Abstract: The device (10) is comprised of a cantilevered beam (22, 58) positioned above, and free to move relative to, a substrate (24). The beam (22) may carry a plurality of conductors (44, 50) which are insulated from one another. One or more tips (28) is positioned on the beam with each tip being in electrical contact with one of the conductors. A memory device may be constructed by providing an array of such cantilevered beams proximate to a layer of media (16). Devices for positioning the beam in x and y directions (30, 32, 34, 36) perpendicular to each other and parallel to the layer of media and in a z direction (26, 68, 70) perpendicular to the media are provided. A control circuit (14) generates control signals input to the positioning devices for positioning the tips according to x, y and z coordinates. A read/write circuit (14) which is in electrical communication with the conductors of the beam, provide signals to the tips to cause the tips to write those signals to the layer of media in a write mode and to read previously written signals sensed by the tips in a read mode. A fabrication method is also disclosed.

    Abstract: A microelectronic device comprises local digit line structures, global digit line structures, source line structures, sense transistors, read transistors, and write transistors. The local digit line structures are coupled to strings of memory cells. The global digit line structures overlie the local digit line structures. The source line structures are interposed between the local digit line structures and the global digit line structures. The sense transistors are interposed between the source line structures and the global digit line structures, and are coupled to the local digit line structures and the source line structures. The read transistors are interposed between and are coupled to the sense transistors and the global digit line structures. The write transistors are interposed between and are coupled to the global digit line structures and the local digit line structures. Additional microelectronic devices, memory devices, and electronic systems are also described.

    Abstract: A method is disclosed for forming a single crystal cantilever and tip on a substrate. The method can include the operation of defining an implant area on the substrate with a layer of photoresist. A further operation can be implanting oxygen into the substrate in the implant area to a predetermined depth to form a buried oxide layer. The buried oxide layer can define a bottom of the single crystal cantilever and tip. Another operation can involve shaping the single crystal cantilever and tip from the substrate above the buried oxide layer.
