Abstract:
Embodiments may include an eFuse cell. The eFuse cell may include an eFuse having a first end and a second end. A blowFET has a first source/drain area, a second source/drain area, and a first gate. The first source/drain area is coupled to the second end of the eFuse, the second source/drain area is coupled to ground, and the first gate is coupled to a first node. The eFuse cell includes a senseFET having a third source/drain area, a fourth source/drain area, and a second gate. The second gate is coupled to the first node, and the third source/drain area is coupled to a second node. The second node is coupled to an operation signal and the second end of the eFuse. The eFuse cell includes a select eFuse logic element having an input to receive a select eFuse signal and an output coupled to the first node.
