| 1. An electrical fuse programming circuit, comprising:
a first path including a bypass resistor in series with a first transistor, wherein the first path includes no fuse elements;
a second path, connected in parallel with said first path, including a fuse element in series with a second transistor; and
logic circuitry for causing current to sequentially and instantaneously flow through only the first path during a first time
period and then flow through only the second path during a second time period immediately following said first time period.
