Abstract:
1. A driver set for a cross point memory array comprising: a semiconductor substrate with an active surface in the x-direction and y-direction directions; a plurality of line driver groups formed on the active surface of the substrate and stacked in the y-direction, each line driver group having transistors in various positions; a plurality of y-direction lines on a first fabrication layer above the active surface of the semiconductor substrate, each y-direction line electrically connecting the transistors of a line driver group to transistors of other line driver groups that share the same relative position; a plurality of first x-direction lines on a second fabrication layer above the active surface of the semiconductor substrate that electrically connects the transistors of a line driver group to each other; a plurality of second x-direction lines on the second fabrication layer, each second x-direction line electrically connecting the line drivers in each line driver group; a plurality of third x-direction lines on the second fabrication layer, each third x-direction line electrically connected to a single line driver.
