ABSTRACT:
An apparatus, a method, and a system for fuse cells are disclosed herein. In various embodiments, a fuse cell may include circuitry to adjust a sensing margin. A fuse cell may include first and second fuse cells, and first and second resistance devices. The first resistance device may be configured to adjust a first voltage output from the first fuse cell, and the second resistance device may be configured to adjust a second voltage output from the second fuse cell. The first and second resistance devices may be configured adjust the first and second voltages asymmetrically.
