Some embodiments include memory cells which have multiple programmable material structures between a pair of electrodes. One of the programmable material structures has a first edge, and another of the programmable material structures has a second edge that contacts the first edge. Some embodiments include methods of forming an array of memory cells. First programmable material segments are formed over bottom electrodes. The first programmable material segments extend along a first axis. Lines of second programmable material are formed over the first programmable material segments, and are formed to extend along a second axis that intersects the first axis. The second programmable material lines have lower surfaces that contact upper surfaces of the first programmable material segments. Top electrode lines are formed over the second programmable material lines.

摘要:
A magnetic memory cell including a soft magnetic layer and a coupling layer, and methods of operating the memory cell are provided. The memory cell includes a stack with a free ferromagnetic layer and a pinned ferromagnetic layer, and a soft magnetic layer and a coupling layer may also be formed as layers in the stack. The coupling layer may cause antiferromagnetic coupling to induce the free ferromagnetic layer to be magnetized in a direction antiparallel to the magnetization of the soft magnetic layer, or the coupling layer may cause ferromagnetic coupling to induce the free ferromagnetic layer to be magnetized in a direction parallel to the magnetization of the soft magnetic layer. The coupling layer, through a coupling effect, reduces the critical switching current of the memory cell.
摘要:
Electrical contacts may be formed by forming dielectric liners along sidewalls of a dielectric structure, forming sacrificial liners over and transverse to the dielectric liners along sidewalls of a sacrificial structure, selectively removing portions of the dielectric liners at intersections of the dielectric liners and sacrificial liners to form pores, and at least partially filling the pores with a conductive material. Nano-scale pores may be formed by similar methods. Bottom electrodes may be formed and electrical contacts may be structurally and electrically coupled to the bottom electrodes to form memory devices. Nano-scale electrical contacts may have a rectangular cross-section of a first width and a second width, each width less than about 20 nm. Memory devices may include bottom electrodes, electrical contacts having a cross-sectional area less than about 150 nm2 over and electrically coupled to the bottom electrodes, and a cell material over the electrical contacts.
摘要:
Iron-sulfide redox flow battery (RFB) systems can be advantageous for energy storage, particularly when the electrolytes have pH values greater than 6. Such systems can exhibit excellent energy conversion efficiency and stability and can utilize low-cost materials that are relatively safer and more environmentally friendly. One example of an iron-sulfide RFB is characterized by a positive electrolyte that comprises Fe(III) and/or Fe(II) in a positive electrolyte supporting solution, a negative electrolyte that comprises S2− and/or S in a negative electrolyte supporting solution, and a membrane, or a separator, that separates the positive electrolyte and electrode from the negative electrolyte and electrode.
