    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 memory system includes a plurality of non-volatile storage elements that each comprise a diode (or other steering device) in series with reversible resistance-switching material. One or more circuits in the memory system program the non-volatile storage elements by changing the reversible resistance-switching material of one or more non-volatile storage elements to a first resistance state. The memory system can also change the reversible resistance-switching material of one or more of the non-volatile storage elements from the first resistance state to a second resistance state by applying one or more pairs of opposite polarity voltage conditions (e.g., pulses) to the respective diodes (or other steering devices) such that current flows in the diodes (or other steering devices) without operating the diodes (or other steering devices) in breakdown condition.

    摘要: Non-volatile memory transistors are provided that include a floating gate formed from first and second layers of material such as polysilicon. The second floating gate layer is selectively grown or deposited on top of the first gate layer, eliminating the need to mask for positioning of the second floating gate layer. The memory transistors are separated by isolation regions. The second floating gate layer overlaps portions of the isolation regions to provide a high control gate-to-floating gate coupling ratio. The process enables smaller memory transistors. Floating gate to isolation overlap, and therefore floating gate to floating gate spacing, is controlled by selective deposition or selective epitaxial growth of the second polysilicon layer.
