How sram based fpga differs from anti fuse based fpga?

SRAM-based FPGAs use static random-access memory cells to store configuration data, allowing for reprogrammability and flexibility in design changes. In contrast, antifuse-based FPGAs utilize a one-time programmable technology where connections are made by creating permanent links during the programming process. This means that while SRAM FPGAs can be reconfigured multiple times, antifuse FPGAs are set once and cannot be altered afterward. Consequently, SRAM-based FPGAs are often favored for applications requiring frequent updates, while antifuse FPGAs may be preferred for their security and reliability in fixed-function applications.
