Abstract:
A margin restore fuse element is described, including a latch configured to store data, a first memory element coupled to the latch and configured to store a first resistive value, a second memory element coupled to the latch and configured to store a second resistive value, a restore circuit coupled to the latch, the first memory element, and the second memory element, the restore circuit being configured to perform a restore data operation to substantially restore the first and second memory elements to the first and second resistive values, respectively. The latch, restore circuit, and other circuitry can be formed FEOL on a substrate (e.g., a semiconductor wafer) as part of a microelectronics fabrication process and the fuse element and memory elements can be formed BEOL over the substrate as part of another microelectronics fabrication process. The fuse and memory elements can be included in a two-terminal non-volatile memory cell.
