Abstract
A transistor (such as a MOSFET) is operated with the well biased, as opposed to being grounded, to program an electric fuse. With the programming transistor operated with an active well bias, more energy is enabled for programming the fuse than is available with a grounded well for the same size transistor. Thus, a smaller transistor can be used of programming the fuse. In a multiple fuse embodiment, the programming transistors can be arranged in the same “well” with a common independent Vbias applied, via a body control circuit, to the entire well during programming of a select fuse.
