Abstract: The present disclosure generally relates to multi-switch storage cells (MSSCs), three-dimensional MSSC arrays, and three-dimensional MSSC memory. Multi-switch storage cells include a cell select device, multiple resistive change elements, and an intracell wiring electrically connecting the multiple resistive change elements together and to the cell select device. MSSC arrays are designed (architected) and operated to prevent inter-cell (sneak path) currents between multi-switch storage cells, which prevents stored data disturb from adjacent cells and adjacent cell data pattern sensitivity. Additionally, READ and WRITE operations may be performed on one of the multiple resistive change elements in a multi-switch storage cell without disturbing the stored data in the remaining resistive change elements. However, controlled parasitic currents may flow in the remaining resistive change elements within the cell. Isolating each multi-switch storage cell in a three-dimensional MSSC array, enables in-memory computing for applications such as data processing for machine learning and artificial intelligence.

Abstract: A molecular memory recording molecular polarization of a single-molecule electret, and the single-molecule electret includes a cluster skeleton 100 having a continuous hole 101 and a plurality of stable ionic sites 102a, 102b and a metal ion M. The molecular polarization is shown in a state in which the metal ion is included in the stable ionic site. The molecular polarization is changed by movement of the metal ion to the other hollow stable ionic site by application of an electric field. The recordkeeping time of the molecular memory in a temperature range of −100° C. to 100° C. based on the ion radius of the metal ion is 3.0×10−2 seconds to 9.1×1022 seconds. Based on the recordkeeping time, the molecular memory is used as any of a volatile memory, a non-volatile memory, and a storage class memory.

Abstract: A nanostructured cross-wire memory architecture is provided that can interface with conventional semiconductor technologies and be electrically accessed and read. The architecture links lower and upper sets of generally parallel nanowires oriented crosswise, with a memory element that has a characteristic conductance. Each nanowire end is attached to an electrode. Conductance of the linkages in the gap between the wires encodes the information. The nanowires may be highly-conductive, self-assembled, nucleic acid-based nanowires enhanced with dopants including metal ions, carbon, metal nanoparticles and intercalators. Conductance of the memory elements can be controlled by sequence, length, conformation, doping, and number of pathways between nanowires. A diode can also be connected in series with each of the memory elements. Linkers may also be redox or electroactive switching molecules or nanoparticles where the charge state changes the resistance of the memory element.
