Abstract
Electrical fuses (eFuses) are applied to the task of memory performance adjustment to improve upon earlier fuse techniques by not requiring an additional processing step and expensive equipment. Standard electrical fuse (eFuse) hardware chains provide a soft test feature wherein the effect of memory slow-down can be tested prior to actually programming the fuses. Electrical fuses thus provide a very efficient non-volatile method to match the logic-memory interface through memory trimming, drastically cutting costs and cycle times involved.
