Circular printed memory system and method having robustness to orientation

A memory system, comprising:

• a circular memory device, comprising:
• a plurality of bottom electrodes comprising a plurality of bottom electrode contact pads and a plurality of bottom electrode extended members, wherein:
• each of the plurality of bottom electrode contact pads is in electrical communication with one of the bottom electrode extended members;
• each of the plurality of bottom electrode contact pads comprises a first arc-shaped midline bisecting the bottom electrode contact pad and positioned at a first radius from a center of the circular memory device;
• and
• a perimeter of each bottom electrode contact pad defines an annular sector bisected by the first arc-shaped midline;
• a plurality of top electrodes comprising a plurality of top electrode contact pads and a plurality of top electrode extended members, wherein:
• each of the plurality of top electrode contact pads is in electrical communication with one of the top electrode extended members;
• each of the plurality of top electrode contact pads comprises a second arc-shaped midline bisecting the top electrode and positioned at a second radius from the center of the circular memory device, wherein the first radius is different from the second radius;
• and
• a ferroelectric layer positioned between the plurality of bottom electrode extended members and the plurality of top electrode extended members;
• and
• a reader configured to perform a memory operation on the circular memory device, the reader comprising a plurality of probes configured to electrically couple to the plurality of bottom electrode contact pads and the plurality of top electrode contact pads.
