Which of the following is not true about SRAM based FPGAs?
- A. They are reprogrammable
- B. They require external configuration memory
- C. Configuration is held in SRAM
- D. They have less power consumption compared to Flash FPGAs
Answer: D. They have less power consumption compared to Flash FPGAs
Explanation: SRAM-based FPGAs are volatile and reprogrammable, holding configuration in SRAM cells, and requiring external non-volatile memory (like Flash or EEPROM) to boot up upon power-on. However, SRAM FPGAs generally consume *more* static (leakage) power than Flash-based FPGAs because the SRAM cells constantly draw power to maintain their state.
