摘要: It is sometimes desirable to encrypt a design for loading into PLD so that an attacker may not learn and copy the as it being copied PLD. According invention, encrypted decrypted by key or keys within are preserved when power removed either stored in nonvolatile memory backed up with battery switches operation from
