    摘要: Optimized electrodes for ReRAM memory cells and methods for forming the same are discloses. One aspect comprises forming a first electrode, forming a state change element in contact with the first electrode, treating the state change element, and forming a second electrode. Treating the state change element increases the barrier height at the interface between the second electrode and the state change element. Another aspect comprises forming a first electrode in a manner to deliberately establish a certain degree of amorphization in the first electrode, forming a state change element in contact with the first electrode. The degree of amorphization of the first electrode is either at least as great as the degree of amorphization of the state change element or no more than 5 percent less than the degree of amorphization of the state change element.

    摘要: Non-volatile storage elements having a reversible resistivity-switching element and techniques for fabricating the same are disclosed herein. The reversible resistivity-switching element may be formed by depositing an oxygen diffusion resistant material (e.g., heavily doped Si, W, WN) over the top electrode. A trap passivation material (e.g., fluorine, nitrogen, hydrogen, deuterium) may be incorporated into one or more of the bottom electrode, a metal oxide region, or the top electrode of the reversible resistivity-switching element. One embodiment includes a reversible resistivity-switching element having a bi-layer capping layer between the metal oxide and the top electrode. Fabricating the device may include depositing (un-reacted) titanium and depositing titanium oxide in situ without air brake. One embodiment includes incorporating titanium into the metal oxide of the reversible resistivity-switching element. The titanium might be implanted into the metal oxide while depositing the metal oxide, or after deposition of the metal oxide. Sub-plantation may be used to create a titanium region between two metal oxide regions.

    摘要: A storage system and method for forming a storage system that uses punch-through diodes as a steering element in series with a reversible resistivity-switching element is described. The punch-through diode allows bipolar operation of a cross-point memory array. The punch-through diode may have a symmetrical non-linear current/voltage relationship. The punch-through diode has a high current at high bias for selected cells and a low leakage current at low bias for unselected cells. Therefore, it is compatible with bipolar switching in cross-point memory arrays having resistive switching elements. The punch-through diode may be a N+/P−/N+ device or a P+/N−/P+ device.

    摘要: During the manufacture of a set of non-volatile resistance-switching memory elements, a forming process is performed in which a voltage is applied over forming period until a conductive filament is formed in a resistance-switching layer. A heat source at a temperature of 50° C. to 150° C. is applied to expedite the forming process while reducing the required magnitude of the applied voltage. Manufacturing time and reliability are improved. After the forming process, an expedited training process can be performed in which a fixed number of cycles of voltage pulses are applied without verifying the memory elements. Subsequently, the memory elements are verified by determining their read current in an evaluation. Another fixed number of cycles of voltage pulses is applied without verifying the memory elements, if the memory elements do not pass the evaluation.
