Abstract
A memory device with multi-bit memory cells and method of making the same uses self-assembly to provide polymer memory cells on the contacts to a transistor array. Employing self-assembly produces polymer memory cells at the precise locations of the contacts of the transistor array. The polymer memory cells change resistance values in response to electric current above a specified threshold value. The memory cells retain the resistivity values over time.
Claims17
A memory device, comprising:
- an addressable array of transistors;
- a dielectric layer covering the transistor array;
- a plurality of contacts to the transistor array through the dielectric layer with at least some of the contacts exposed, the exposed contacts comprising a conductive plug extending from the transistor towards a top surface of the dielectric layer, a barrier layer on a top of the conductive plug, and an adhesion layer on the barrier layer;
- memory elements on at least some of the contacts, with the memory elements being formed only on the contacts and not on the dielectric layer;
- and
- a common electrode contacting each of the memory elements.
