Abstract
An electrical fuse programming circuit and a method for programming an electrical fuse within the electrical fuse programming circuit use a programming circuit bus to which are electrically connected in parallel the electrical fuse and a bypass resistor. A current within the programming circuit bus is made to flow through the bypass resistor for a period of time sufficient to stabilize the current, and then sequentially and instantaneously switched to program the electrical fuse.
