INTEGRATED CIRCUIT STRUCTURE, METHOD FOR FABRICATING INTEGRATED CIRCUIT CONNECTION DEVICE, METHOD FOR FABRICATING CIRCUIT, ADDRESSING CIRCUITRY, AND METHOD FOR FABRICATING ADDRESSING CIRCUITRY

摘要

PURPOSE: An addressing circuitry is provided to access a memory device in a crossing-point diode memory array by creating circuit elements at the crossing-points of two layers of electrode conductors that are separated by a layer of a semiconductor material. CONSTITUTION: The circuit elements formed at the crossing-points functions as data storage devices in the memory array, and function as connections for a permuted addressing scheme for addressing the elements in the memory array. The electrode conductors are fabricated with a controlled geometry at selected crossing-points such that selected circuit elements have increased or decreased cross-sectional area, so that the addressing circuitry is constructed. The electrical characteristics(e.g. resistance) of selected circuit elements can be changed according to the controlled electrode geometry by applying a programming electrical signal to the electrodes.
