    摘要: In an embodiment, a non-volatile memory array wherein narrow word lines, as small as the minimum feature size width F, in separate strings, are extended outwardly from a non-volatile memory array and joined by wider connector segments. The joined word lines provide new opportunities. First, metal straps that can be formed to overlie the word lines can be joined by metal connector segments to the word lines. The connector segments can serve as an interface between the polysilicon word lines and the metal straps. Two adjacent word lines in the same string share a single metal strap using these segments thereby reducing the overall number of segments and contacts in the array. Increased width of the polysilicon joinder segments joining word lines in different strings, provides the opportunity for widening the connection beyond the minimum feature size so that contact may be readily made between the metal straps and the polysilicon word lines. Second, the joined word lines require fewer row decoder circuits. One row decoder is provided for each joined set of word lines.

    摘要: A flash memory integrated circuit includes a plurality of flash memory arrays. A global word line driver is associated with each array, each global word line driver coupled to a plurality of select lines. A plurality of sense amplifiers are individually coupled to a plurality of bit lines. A plurality of sub arrays in each array each include a plurality of NAND flash memory cells coupled to local word lines and local bit lines. A local word line driver is associated with each sub-array and coupled to the plurality of select lines and configured to drive ones of the local word lines in its sub array associated with selected ones of the plurality of NAND flash memory cells in its sub-array. A local bit line driver is coupled between selected ones of the local bit lines in each sub array and selected ones of the plurality of bit lines.
