Antifuse device behavior State whether the following is accurate: “Antifuse-based programmable logic devices are volatile.”

Introduction / Context:Antifuse technology creates permanent conductive links when programmed. Understanding volatility is essential for configuration strategy, security, and mission-critical applications.

Given Data / Assumptions:

• Technology: antifuse (one-time programmable).
• Claim: antifuse devices are volatile.
• We evaluate based on how antifuse stores configuration.

Concept / Approach:Volatile devices lose their configuration when power is removed. Antifuse devices, by contrast, physically alter the silicon by shorting specific structures during programming, creating permanent connections that persist without power. Thus, antifuse devices are non-volatile and one-time programmable (OTP). This permanence is advantageous for tamper resistance and radiation tolerance but precludes reprogramming.

Step-by-Step Solution:Recall definition: volatility means configuration disappears on power loss.Antifuse programming forms permanent physical links.Therefore, antifuse devices are non-volatile; the claim is incorrect.

Verification / Alternative check:Vendor documentation consistently emphasizes OTP, non-volatile behavior for antifuse FPGAs and structured PLDs.

Why Other Options Are Wrong:Temperature or power-cycle caveats do not change the fundamental non-volatile nature; once programmed, the conductive link remains.

Common Pitfalls:Confusing antifuse with SRAM configuration (volatile) or flash-based non-volatile solutions; assuming all programmable logic loads configuration at power-up from external memory.

Final Answer:Incorrect
