Abstract
An active fuse includes an active fuse geometry () that is used to form both a variable resistor () and a select transistor (). In one embodiment, the active fuse geometry is formed in a portion of an active region () of a semiconductor substrate (), and a select gate () is disposed over an end portion () of the active fuse geometry to form an integral select transistor () for use in programming the active fuse. The use of a shared active fuse geometry within the active region allows for reduced area requirements and improved sensing margins.
