1. polymer memory comprises:

  • First many aluminium word lines, described word line extends parallel to each other along the y direction, and has at the be spaced apart from each other center line of first distance of x direction, and the width of wherein said aluminium word line on the x direction is half of described first distance;

    On described word line along first ferroelectric polymer memory material of x direction and y direction;

    Many conductive bit, described bit line extends parallel to each other along described x direction on described first ferroelectric polymer memory material, and have at the be spaced apart from each other center line of second distance of described y direction, described second distance is half of described second distance less than described first distance and the width of described conductive bit on the y direction, in described first ferroelectric polymer memory material, limit the first polymer memory cell array, each polymer memory cell in the described first polymer memory cell array is in respective bit line in a wherein corresponding place that intersects of described first many aluminium word lines, when voltage difference being put on respective word on the opposition side of corresponding units of the described first polymer memory cell array and bit line with box lunch, described first ferroelectric polymer memory material at the described corresponding units place of the described first polymer memory cell array is changed, and the layer that wherein has the conductive bit of the center line with spaced apart described second distance accounts for 50% the ratio of being less than of described aluminium word line and conductive bit layer.
