Abstract:
A method of forming metal line segments for a simultaneous operation flash memory device with a flexible bank partition architecture, the method comprising the steps of:(a) providing a plurality of basic metal layer segments separated by a plurality of gaps, each of the gaps having a predefined gap interval length; and(b) providing a metal option layer comprising a plurality of metal option layer segments on the basic metal layer segments, each of the metal option layer segments having a length at least as much as the gap interval length of a respective one of the gaps between the basic metal layer segments, the metal option layer segments overlapping some of the gaps between the basic metal layer segments but leaving one of the gaps open, to form a conductive path between the gaps except the one of the gaps which is left open, the basic metal layer segments and the metal option layer segments together forming first and second metal line segments for the simultaneous operation flash memory device with the flexible bank partition architecture.
