Abstract
A method of reading an eFuse in a column of eFuse memory cells includes electrically disconnecting a first end of the eFuse from a first electrical path. A second electrical path between a second end of the eFuse and a node is activated to bypass a third electrical path, where the third electrical path includes a diode device between the second end of the eFuse and the node. A footer coupled with the node is turned on.
