    摘要: A memory cell device, of the type that includes a memory material switchable between electrical property states by application of energy, includes first and second electrodes, a plug of memory material (such as phase change material) which is in electrical contact with the second electrode, and an electrically conductive film which is supported by a dielectric form and which is in electrical contact with the first electrode and with the memory material plug. The dielectric form is wider near the first electrode, and is narrower near the phase change plug. The area of contact of the conductive film with the phase change plug is defined in part by the geometry of the dielectric form over which the conductive film is formed. Also, methods for making the device include steps of constructing a dielectric form over a first electrode, and forming a conductive film over the dielectric form.

    摘要: A bistable resistance random access memory is described for enhancing the data retention in a resistance random access memory member. A dielectric member, e.g. the bottom dielectric member, underlies the resistance random access memory member which improves the SET/RESET window in the retention of information. The deposition of the bottom dielectric member is carried out by a plasma-enhanced chemical vapor deposition or by high-density-plasma chemical vapor deposition. One suitable material for constructing the bottom dielectric member is a silicon oxide. The bistable resistance random access memory includes a bottom dielectric member disposed between a resistance random access member and a bottom electrode or bottom contact plug. Additional layers including a bit line, a top contact plug, and a top electrode disposed over the top surface of the resistance random access memory member. Sides of the top electrode and the resistance random access memory member are substantially aligned with each other.

    摘要: A memory device includes an access device including a first doped semiconductor region having a first conductivity type, and a second doped semiconductor region having a second conductivity type opposite the first conductivity type. Both the first and the second doped semiconductor regions are formed in a single-crystalline semiconductor body, and define a p-n junction between them. The first and second doped semiconductor regions are implemented in isolated parallel ridges formed in the single-crystal semiconductor body. Each ridge is crenellated, and the crenellations define semiconductor islands; the first doped semiconductor region occupies a lower portion of the islands and an upper part of the ridge, and the second doped semiconductor region occupies an upper portion of the islands, so that the p-n junctions are defined within the islands.

    摘要: A resistance random access memory in a bridge structure is disclosed that comprises a contact structure where first and second electrodes are located within the contact structure. The first electrode has a circumferential extending shape, such as an annular shape, surrounding an inner wall of the contact structure. The second electrode is located within an interior of the circumferential extending shape and separated from the first electrode by an insulating material. A resistance memory bridge is in contact with an edge surface of the first and second electrodes. The first electrode in the contact structure is connected to a transistor and the second electrode in the contact structure is connected to a bit line. A bit line is connected to the second electrode by a self-aligning process.
