    Abstract: A memory array having memory cells comprising a diode and an antifuse can be made smaller and programmed at lower voltage by using antifuse materials having higher dielectric constant and higher acceleration factor than silicon dioxide, and by using diodes having lower band gaps than silicon. Such memory arrays can be made to have long operating lifetimes by using the high acceleration factor and lower band gap materials. Antifuse materials having dielectric constants between 5 and 27, for example hafnium silicon oxynitride or hafnium silicon oxide are particularly effective. Diode materials with band gaps lower than silicon, such as germanium or a silicon-germanium alloy are particularly effective.

    Abstract: 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.

    Abstract: A three-dimensional (3D) passive element memory cell array provides short word lines while still maintaining a small support circuit area for efficiency. Short, low resistance word line segments on two or more word line layers are connected together in parallel to form a given word line without use of segment switch devices between the word line segments. A shared vertical connection preferably connects the word line segments together and connects to a word line driver circuit disposed generally below the array near the word line. Each word line driver circuit preferably couples its word line either to an associated one of a plurality of selected bias lines or to an unselected bias line associated with the driver circuit, which selected bias lines are themselves decoded to provide for an efficient multi-headed word line decoder.
