Questions & Answers

Q: What are the primary programming technologies discussed in the video?

The video highlights three main programming technologies used in FPGAs: SRAM (Static Random Access Memory), anti-fuse technology, and EEPROM (Electrically Erasable Programmable Read-Only Memory). SRAM is known for its volatile nature, anti-fuse for its one-time programmable capability, and EEPROM allows data to be erased and reprogrammed multiple times.

Q: What is the significance of SRAM in FPGA technology?

SRAM plays a critical role in FPGA technology as it allows for temporary data storage and easy reprogramming. It is volatile, meaning that the stored data is lost when power is removed, requiring reprogramming during each power-up. Its configuration facilitates dynamic reconfiguration, enabling changes to logic functions without needing to halt operations.

Q: How many transistors are involved in a standard SRAM cell as explained in the video?

Each SRAM cell is composed of six transistors, which include two CMOS inverters connected back to back and additional pass transistors. This configuration not only stores data temporarily but also allows for effective data transfer and operation within the FPGA architecture.

Q: What happens to SRAM data when power is lost?

When power is lost, the data stored in SRAM is erased, as it is classified as volatile memory. This means that, upon power restoration, the SRAM needs to be reprogrammed to establish the necessary logic functions again since the previous data cannot be retrieved.
