    摘要: Semiconductor memory devices, resistive memory devices, memory cell structures, and methods of forming a resistive memory cell are provided. One example method of a resistive memory cell can include a number of dielectric regions formed between two electrodes, and a barrier dielectric region formed between each of the dielectric regions. The barrier dielectric region serves to reduce an oxygen diffusion rate associated with the dielectric regions.

    摘要: Some embodiments include memory structures having a diode over a memory cell. The memory cell can include programmable material between a pair of electrodes, with the programmable material containing a multivalent metal oxide directly against a high-k dielectric. The diode can include a first diode electrode directly over one of the memory cell electrodes and electrically coupled with the memory cell electrode, and can include a second diode electrode laterally outward of the first diode electrode and not directly over the memory cell. Some embodiments include memory arrays comprising the memory structures, and some embodiments include methods of making the memory structures.

    摘要: A transistor device includes a pair of source/drain regions having a channel region there-between. A first gate is proximate the channel region. A gate dielectric is between the first gate and the channel region. A second gate is proximate the channel region. A programmable material is between the second gate and the channel region. The programmable material includes at least one of a) a multivalent metal oxide portion and an oxygen-containing dielectric portion, or b) a multivalent metal nitride portion and a nitrogen-containing dielectric portion. Memory cells and arrays of memory cells are disclosed.
