    摘要: A method, system, and computer software product for operating a memory cell collection. Memory cells in the collection store binary multi-bit values delimited by characteristic parameter bands of a characteristic parameter. In one embodiment, a comparing unit compares a retrieved count and a stored count for each binary multi-bit value. The retrieved count, equal to the number of occurrences the binary multi-bit value, is retrieved from the memory cell collection. The stored count, equal to the number of occurrences the binary multi-bit value, is stored in the memory cell collection. An error correction unit then assigns the error memory cell(s) a corrected binary multi-bit value with the characteristic parameter value within the characteristic parameter band adjacent to the characteristic parameter band associated with the retrieved binary multi-bit value such that the retrieved count of each binary multi-bit value is equal to the stored count of each binary multi-bit value.

    摘要: A semiconductor structure that includes two programmable vias each of which contains a phase change material that is integrated with a heating material. In particular, the present invention provides a structure in which two programmable vias, each containing a phase change material, are located on opposing surfaces of a heating material. Each end portion of an upper surface of the heating material is connected to a metal terminal. These metal terminals, which are in contact with the end portions of the upper surface of the heating material, can be each connected to an outside component that controls and switches the resistance states of the two programmable vias. The two programmable vias of the inventive structure are each connected to another metal terminal. These metal terminals that are associated with the programmable vias can be also connected to a circuit block that may be present in the structure.

    摘要: According to the preferred embodiment, an antifuse structure and method for personalizing a semiconductor device is provided that overcomes the limitations of the prior art. The preferred embodiment antifuse comprises a two layer transformable insulator core between two electrodes. The transformable core is normally non-conductive but can be transformed into a conductive material by supplying a sufficient voltage across the electrodes. The two layer core preferably comprises an injector layer and a dielectric layer. The injector layer preferably comprises a two phase material such as silicon rich nitride or silicon rich oxide. Initially, the injector layer and dielectric layer are non-conductive. When a sufficient voltage is applied the core fuses together and becomes conductive.
