一次性编程FPGA主要采用反熔丝开关元件，具有体积小低，抗辐射，抗干扰

One-time programming FPGA mainly uses anti-fuse switching elements, which have the characteristics of small size and low size, anti-radiation, anti-interference, etc., without external BROM or EPROM, circuit configuration data will not be lost after power off, and it can work after power on. Among such products, ACTEL’s anti-radiation hardened anti-fuse FPGA has already gained experience in aerospace applications. Compared with the traditional FPGA, the anti-fuse FPGA adopts a compact grid and densely arranged planar logic module. The structure uses the internal connection elements of the metal-to-metal anti-fuse between the upper and lower logic module layers to realize the connection of the devices. Reduce the space occupied by the channel and wiring resources. Programming makes the small area of ​​the anti-fuse structure have a sufficiently high current density, and instantaneously generates a large thermal power consumption to melt the dielectric layer of the insulating layer, and form a permanent path.
