ALL-PRINTED PAPER MEMORY

摘要

All-printed paper-based substrate memory devices are described. In an embodiment, a paper-based memory device is prepared by coating one or more areas of a paper substrate with a conductor material such as a carbon paste, to form a first electrode of a memory, depositing a layer of insulator material, such as titanium dioxide, over one or more areas of the conductor material, and depositing a layer of metal over one or more areas of the insulator material to form a second electrode of the memory. In an embodiment, the device can further include diodes printed between the insulator material and the second electrode, and the first electrode and the second electrodes can be formed as a crossbar structure to provide a WORM memory. The various layers and the diodes can be printed onto the paper substrate by, for example, an ink jet printer.

主权项

1. A method of forming a paper-based substrate memory device, comprising:
coating one or more areas of a paper substrate with a conductor material to form a first electrode of the memory device; depositing, with the least one printer, a layer of an insulator material over one or more areas of the conductor material; depositing, with at least one printer, at least one diode onto the insulator material; and depositing, with the least one printer, a layer of a metal over the at least one diode of the insulator material to form a second electrode of the memory device.
