Electronic fuse apparatus and methodology including addressable virtual electronic fuses |
摘要 |
A virtual electronic fuse (VEF) apparatus and methodology are disclosed that permit the state of an electronic fuse to change from an un-blown state to a blown state and then back to a virtual un-blown state. In one embodiment, the electronic fuse may change from the virtual un-blown state back again to a virtual blown state. The fuse apparatus includes multiple VEFs, each VEF exhibiting a respective address. The fuse apparatus also includes an address pool including multiple address pool locations. A fuse programmer stores an address of one of the VEFs in one or more address pool locations to indicate one or more state changes for a particular VEF. The fuse programmer may also store different VEF addresses in different address pool locations to indicate state changes for different VEFs. |
