1. A one-time programmable memory array comprising:
- a first row conductor extending in a first row direction and disposed at a first elevation;
a second row conductor extending in a second row direction and disposed at a second elevation;
a column conductor extending in a column direction and disposed adjacent to the first row conductor and adjacent to the second row conductor, the column direction being different from the first and second row directions;
a dielectric layer covering at least a portion of the column conductor; and
a fuse link coupled between the dielectric layer on the column conductor and the second row conductor.
