A system and method are disclosed for processing an organic memory cell. An exemplary system can employ an enclosed processing chamber, a passive layer formation component operative to form a passive layer on a first electrode, and an organic semiconductor layer formation component operative to form an organic semiconductor layer on the passive layer. A wafer substrate is not needed to transfer from a passive layer formation system to an organic semiconductor layer formation system. The passive layer is not exposed to air after formation of the passive layer and before formation of the organic semiconductor layer. As a result, conductive impurities caused by the exposure to air do not occur in the thin film layer, thus improving productivity, quality, and reliability of organic memory devices. The system can further employ a second electrode formation component operative to form a second electrode on the organic semiconductor layer.

System and method for processing an organic memory cell

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.

Memory device with a self-assembled polymer film and method of making the same

Systems and methodologies are provided for simplifying a polymer memory cell's operation by employing a post polymer growth treatment to form ionic or super ionic metal compounds therein. Such post polymer growth treatment facilitates distribution and mobility of metal ions (or charged metallic molecules) within an active layer of the polymer memory cell, and mitigates (or eliminates) a need for initialization procedures. Moreover, the post treatment of the present invention can also facilitate controlling a distribution of various thresholds (e.g., write and erase threshold), and set them to predetermined values Accordingly, variability in threshold values of polymer memory cells that can result from initialization processes can be mitigated (or eliminated), and thicker polymer layers can be employed without an initialization penalty.

Method to improve yield and simplify operation of polymer memory cells

A memory cell is provided with a pair of electrodes, and an active layer sandwiched between the electrodes and including a molecular system and ionic complexes distributed in the molecular system. The active layer having a high-impedance state and a low-impedance state switches from the high-impedance state to the low-impedance state when an amplitude of a writing signal exceeds a writing threshold level, to enable writing information into the memory cell. The active layer switches from the low-impedance state to the high-impedance state when an amplitude of an erasing signal having opposite polarity with respect to the writing signal exceeds an erasing threshold level, to enable erasing information from the memory cell.

Molecular memory cell

Methods and systems are provided for patterning a non conductive dielectric on a surface of a conductive polymer. The conductive polymer can be part of an organic memory cell. Hydrogen ions created form molecular hydrogen being exposed to short wave length radiation, are employed as mobile positive ion charge carriers to create a non-conductive die-electric pattern on a conductive and/or semiconductive polymer surface of the organic memory cell. Such process reduces number of masking steps performed. In addition, the process is scalable with lithographic wave length and can be performed on wide spread tool sets and photoresist material available in commercial market.
