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.

摘要: A non-volatile resistance-switching memory element includes a resistance-switching element formed from a metal oxide layer having a dopant which is provided at a relatively high concentration such as 10% or greater. Further, the dopant is a cation having a relatively large ionic radius such as 70 picometers or greater, such as Magnesium, Chromium, Calcium, Scandium or Yttrium. A cubic fluorite phase lattice may be formed in the metal oxide even at room temperature so that switching power may be reduced. The memory element may be pillar-shaped, extending between first and second electrodes and being in series with a steering element such as a diode. The metal oxide layer may be deposited at the same time as the dopant. Or, using atomic layer deposition, an oxide of a first metal can be deposited, followed by an oxide of a second metal, followed by annealing to cause intermixing, in repeated cycles.
