* Question
| What is blown? |
* Answer
| For a physical fuse, it refers to the process of blowing the fuse inside the chip with an externally increased current.If an E2PROM cell is used to indicate a fuse signal, fusing refers to a write operation to the cell.That is, when the unit is 1, the fuse is not blown, and when the unit is 0, the fuse is blown.There are usually two fuses in the chip, as described in Memory Area Allocation and Circuit Design Analysis. |
