20140264243 | NONVOLATIVE MEMORY WITH FILAMENT - An embodiment, relates to a phase changeable memory cell. The phase changeable memory cell is formed with an ultra small contact area formed by filament conductive path. This contact area between a heating electrode and phase changeable material layer is determined by the forming of filament path, which is conductive and much smaller in cross-sectional area than the minimum area that can be achieved by lithography. This leads to high heating efficiency and ultra-low programming current. As the disclosed structure has no requirement on endurance for the formed filament and use phase changeable material rather than filament-forming material to provide high on/off resistance ratio, drawbacks of filament-forming material on low endurance and low sensing margin are avoided in the proposed cell structure. Therefore, by using ReRAM-related filament-forming materials to get sub-litho-dimension conductive path as heating electrode and using high on/off ratio phase changeable material as the storage media, it is possible to reduce the power consumption of phase changeable memory dramatically without the drawbacks of filament-forming materials that are shown in ReRAM. | 09-18-2014 |
20140264244 | NONVOLATIVE MEMORY - A phase changeable memory cell is disclosed. In an embodiment of the invention, a phase changeable memory cell is formed with an ultra-small contact area to reduce the programming current. This contact area between heater electrode and phase changeable material is limited by the thickness of thin films rather than lithographic critical dimension in one dimension. As a result, the contact area is much less than the square of lithographic critical dimension for almost every technology node, which is helps in reducing current. To further reduce the current and improve the heating efficiency, heater electrode is horizontally put with its length being tunable so as to minimize the heat loss flowing through the heater to the terminal that connects to the front end switch device. In addition, above and below the heater layer, low-thermal-conductivity material (LTCM) is used to minimize heat dissipation. This results in reduced power consumption of the phase changeable memory cell with improved reliability. | 09-18-2014 |
